Adblock does not remember filters

[udo]

Environment

Firefox latest on Fedora 24 x86_64: firefox-53.0.2-5.fc24.x86_64
Adblock plus 2.9.
Filter selection does not appear to matter.

How to reproduce

Suddenly I see an advert on youtube.
I try to report an issue.
Then Adblock mentions there are no filter rules.
So I add a few, make a backup (~/filters).
I shut down FF after a while.
I start it up again.
I check the filters: gone.
I try to restore the backup.
Due to a non added extension to ~/filters the file is not recognised.
Renaming it to filters.txt does allow recognition as a custom filter but the file is not accepted.

Observed behaviour

This has been an issue only since recent times, in the past this did work.

Expected behaviour

No forgotten filter rules on startup of FF when previously having insatlled filter rules.

I see the same in SeaMonkey 2.52a1 (built on Gecko 55.0a1) since I the day accepted the update to Adblock Plus 2.9. Previously it had one subscription (Liste FR + Easy List) and one or two custom filters (which I don't remember). Suddenly after the update it told me at next restart "Adblock Plus enabled, 0 filters enabled and 0 filters in use". So I resubscribed to that same filter, but at the next startup it was gone again. Now I've backed it up and added ".ini" at the end of the backup file name. We'll see what happens in the future.

My current SeaMonkey build (where I had this problem) is:

UA:"Mozilla/5.0 (X11; Linux x86_64; rv:55.0) Gecko/20100101 Firefox/55.0 SeaMonkey/2.52a1"

SeaMonkey is #5279 and fixed in development builds. In Firefox this is supposed to work however.

@udo: thank you for reporting this. I cannot see this issue on Ubuntu, and it doesn't seem to be common either. I will test whether there is something special with Firefox on Fedora - but from a quick glance at the package contents there isn't. Just to make sure this isn't an issue with your Firefox profile - could you try a clean profile? You can create a directory like /home/me/testprofile and run Firefox from command line like this: firefox -no-remote --profile /home/me/testprofile. If you install Adblock Plus 2.9 in this profile, are you still having this issue?

[trev]

I've verified that Adblock Plus 2.9 on Fedora 24 x86_64 with firefox-53.0.2-5.fc24.x86_64 is capable of saving data, changes to filters persist. Adblock Plus initialization after browser startup takes a few seconds (Filter Preferences dialog shows up empty while filters are loading) but there is little we can do about that. So please test whether that's something specific to your Firefox profile.

This bug draws attention to the fact that restoring filters is very slow.
It takes seconds for the confirm dialog to appear and then another while has to elapse befor being able to OK the whole thing away from the screen.

What good is it that a profile issue causes this?
It doesn't help me. It doesn't help other users with a similar issue.
It does not fix the occurrence. I do not know what profile issue could cause this issue.
I do not see any messages (where should I look?) when restoring or closing FF that indicate that saving does not work.
Please indicate any logs etc to investigate.

[udo]

Using a different profile in FF does not reproduce the bug.
So what profile content does block writing a copy of the filters to disk?
If such thing happens: why don't we see a fail message about this?
Where is the logging indicating what is happening?

[trev]

This bug draws attention to the fact that restoring filters is very slow.

That's correct of course, but not really relevant here.

What good is it that a profile issue causes this?
It doesn't help me. It doesn't help other users with a similar issue.

The point is narrowing down the issue. If the issue is in your profile, then I can stop trying to reproduce and we can concentrate on your profile.

Could you please type about:support into your Firefox location bar and copy the raw data? Please attach it to this issue then or copy into a post.

There is also a button to open your profile directory on that page. Maybe you can check that directory for incorrect permissions. ​Here is a way to do this from the command line.

There's a quite number of directories with not 755 as permission under my profile dir.
Yet all of them are owned by my user.
Most of these are with 750 permission.
I do not see a problem there.

[trev]

As long as you still have write permission for these directories it should be all fine. In particular, could you verify that you have write access to the browser-extension-data subdirectory of you profile?

Concerning your support data, there is nothing immediately sticking out to me. One thing not covered there are error messages. You could do the following:

• Press Ctrl+Shift+J to open Browser Console
• Click on the trash bin to remove existing messages
• Go back to the browser window, press Ctrl+Shift+A to open Add-ons Manager
• Disable and then enable Adblock Plus

What new messages appear in Browser Console? These might help figuring out what is wrong with Adblock Plus. You can select these can copy them into this issue.

[udo]

browser-extension-data has 700 and my user owning it.

[udo]

I get stuff like this:

Please make the 'Restore Own Backup' dialog disappear immediately after clicking OK. This signals that something is happening.

Why is this 'Restore Own Backup' dialog necessary? The user already chose to restore by selecting a file.

[udo]

In case I didn't provide enough info:
Please let me know how to show the root cause of this issue.

[trev]

Unfortunately, none of this explains why the filters are not being saved for you :-(

Maybe https://issues.adblockplus.org/ticket/5285#comment:5 is the same issue as yours, I'll investigate on Tuesday. Otherwise, the only thing I can offer at this point is a TeamViewer (or any other desktop sharing tool) session.

Seeing cache.js in your directory tree: thank you for staying with us for so long :-)

The user interface can certainly be improved and you can file a separate issue for that. However, it is very unlikely that this issue will be resolved. With the ​current Adblock Plus for Firefox codebase heading towards demolition in a few months, nobody is going to spend time on polishing the user interface any more.

When/how can we test this new type of extension?

Maybe after restoring backups?

Not that this message is particularly helpful, it's a generic message indicating that the original error cause has been lost for some reason.

I'd rather provide you with info and/or run tests.

There isn't a lot of tests I can think of now - I'd need to debug the issue myself, and this is only possible on a computer actually experiencing this issue.

When/how can we test this new type of extension?

As the blog post indicates, you can install a development build already. However, the new options user interface is still being developed and isn't currently part of the build. Also, it will take a while until the backups functionality is implemented, likely isn't going to make the first release...

[trev]

Replying to the question you posted in #5285 (by mistake?): older Adblock Plus versions can be installed under ​https://addons.mozilla.org/addon/adblock-plus/versions/beta. But this most definitely regressed between 4243 and 4244, see ​announcement of this build.

Replying to trev:

I can setup team viewer for you if you want to test it on my test profile which reproduces the issues all the time.

[trev]

Replying to shellye5:

That would be great. I already looked into the error message you quote but as I mentioned above - it's a generic error message merely indicating that the original error cause has been lost. I cannot even tell which exact operation produced that error. Let me know per email (​trev@adblockplus.org) or IRC (palant on ​irc://irc.mozilla.org/#adblockplus) once you have TeamViewer set up.

[JPRuehmann]

I have the same problem
Hope there is a solution in the future.

[trev]

Turned out, shellye5 has "out of memory" errors due to having lots of filter lists - the Web Extension storage is very inefficient, saving data will currently require more memory than a 32-bit process can provide.

udo, JPRuehmann, how many filter lists do you have in Adblock Plus?

[udo]

I do not know what filters I had in use before this issue occurred.
Now I have these five in use and restore them each time from backup:
easylist
easylist Dutch
Peter Lowe's
Blockzilla
Easyprivacy
I tried with just the top two (deleted the others) and shut down FF.
Upon startup all were gone.

[trev]

I confirmed another condition that causes this: if JavaScript is disabled globally, things will break. This is a ​Firefox bug and fixed in Firefox 54. That's not the issue udo is having judging by the about:support info, but maybe JPRuehmann.

[thomaswm]

I can confirm that this happens if the ​RequestPolicy addon is installed and activated. Once I removed that addon, Adblock Plus remembered my filter settings again.

(Tested with Firefox 54.0.1 on Windows 10)

[udo]

Disabling Request policy leaves me indeed with some filters on startup.
So what is the interference?

[dvb]

Guys, I have the same issue with loosing filters on aplication reload on android 4.2 and firefox 54.0.1 and ABP 2.9.1. I use RUAdList+EasyList. No other addons on firefox.

[trev]

Mass-closing all bugs in Adblock Plus for Firefox module, the codebase of Adblock Plus 3.0 belongs into Platform and User-Interface modules. Old bugs are unlikely to still apply.
