1872338 - Opened tabs become inaccessible after reopening Firefox

Status: NEW

(Firefox for Android :: Tabs, defect, P3)

Description

[Charlotte]

Attachment: This is a video of the bug

User Agent: Mozilla/5.0 (Android 11; Mobile; rv:121.0) Gecko/121.0 Firefox/121.0

Steps to reproduce:

It appears to happen randomly, sometimes i can go hours without opening Firefox and everything will work just fine, other times tabs become completely inaccessible.
Sadly, it's the latter that happens more frequently.

Actual results:

After some time of inactivity, Firefox tabs fail to load, leaving me with a grey screen with nothing in it, except my search bar.
Reloading the page does nothing, so I'm forced to reopen it in a different tab.

Expected results:

After reopening Firefox, tabs should have loaded normally.

I also encountered this error, but it doesn't always happen, it rarely happens. You should investigate.

Just today I reproduced this error, on a site that has not been opened for a long time, since I have not opened the tab, I have always deleted data and cookies.

Thanks for reporting this issue and including a screen recording. That's very helpful for understanding the problem!

Does this seem to be a new bug in 121? Or have you seen this in earlier Firefox versions?

Comment 4

[Chris Peterson [:cpeterson]]

When this problem happens, do all your current tabs stop responding or just one?

Comment 5

[eclaudiu64]

For me, when I reproduce this error, it only happens with one tab. This bug is also in previous versions.

hi, this bug was present in previous versions as well.
i've spent some time researching about this issue, and i found out that it was present in way earlier versions than the ones i've used, as well.
the error only happens in one tab, and the only way to fix it is to move to a different one.

is there anything i should do when this problem reappears to make it easier for developers to fix it?
like provide a log or something like that.

i've also never use the nightly build, but i will try to see if the issue persists in that version

[Chris Peterson [:cpeterson]]

I shared this bug report with some Android engineers and they confirmed this is a known issue that affects older versions, too, like you said. Therefore, Firefox Nightly probably has this problem, too.

The engineers haven't been able to reproduce the hangs except for one case involving an add-on.

Do you have any add-ons installed, such as uBlock Origin? Can you share your Firefox's about:support information?

[Charlotte]

I have two add-ons installed: ublock origin and google search fixer.

these are my about:support informations:
