Diễn đàn hỗ trợ Firefox

Hi,

I always have dozens of tabs opened, if not hundreds. They have vanished. I’ve been trying to follow the topics on the matter, such as the one named ‘Session won't load’ (questions/1254740), to no avail.

Finally, this time I remembered not to close Firefox when I saw my tabs where suddenly missing. I’ve never seen the ‘Restore the previous session’ on the Firefox menu, and neither did I this time. Without closing the browser, I did a backup of the ‘sessionstore-backups’ folder. It contains:

‘previous.jsonlz4’, from 22/11/2020 17:42 ‘recovery.baklz4’, from 22/11/2020 18:57 ‘recovery.jsonlz4’ from 22/11/2020 18:58 ‘upgrade.jsonlz4-20201027185343’ from 31/10/2020 13:42 ‘upgrade.jsonlz4-20201108180448’ from 10/11/2020 15:05 ‘upgrade.jsonlz4-20201112153044’ from 22/11/2020 10:34

The one I need is ‘previous.jsonlz4’, since by 18:57 I’ve already lost my tabs. From the update backups I think I could also use the one from 22/11. In any case, I don’t understand what I am doing wrong so as to recover the ‘previous.jsonlz4’. This is what I’ve tried from different threads on my profile folder:

The ‘-backup’ and ‘OLD’ changes belong to different attempts

- Rename (on ‘sessionstore-backups’ folder) ‘recovery.jsonlz4’ and ‘recovery.baklz4’ to ‘recovery-backup.jsonlz4’ and ‘recovery-backup.baklz4’, and also tried with ‘recoveryOLD.jsonlz4’ and ‘recoveryOLD.baklz4’ - Rename ‘sessionstore-backups’ folder to ‘sessionstore-backupsOLD’ - Rename (on the main profile folder) ‘sessionstore.jsonlz4’ file to‘sessionstore-backup.jsonlz4’, and also tried with ‘sessionstoreOLD.jsonlz4’ - Copy/paste the ‘previous.jsonlz4’ file into the main profile folder. - Rename ‘previous.jsonlz4’ to ‘sessionstore.jsonlz4’

Nothing has worked. Once followed the steps, Firefox keeps opening my startup page. Note that it does not restore my previous session (that is, some tabs regarding this same subject), but my startup page, which means my attempts are having some effect, although not the desired one. I do have the ‘Restore previous session’ checkmarked in ‘Setting/General/Startup.

I also tried to replace ‘recovery.baklz4’ (on ‘sessionstore-backups’ folder) with ‘previous.jsonlz4’, from 22/11/2020 17:42, hoping to be prompted with the ‘Well, this is embarrassing’ + ’Restore’ window. I had no success.

I’ve been trying to recover my tabs for hour by now and don’t find what I am doing wrong. Why does Firefox refuse to load my ‘previous.jsonlz4’ file? Am I missing something? Maybe ‘previous.jsonlz4’ is corrupted or something? Should I try to use the ‘upgrade.jsonlz4-20201112153044’ from 22/11/2020 10:34 file? (Although I would lose some information)

Some people talk about a ‘History > Restore Previous Session’. I cannot find anything similar.

Thank you very much

I've recently noticed an issue with Firefox not loading some content for me. On one page it failed to load embedded videos, and when I contacted the site to alert them to the problem they troubleshooted and the issue seemed to be with my browser. A second time, when trying to use Instagram scheduler Planoly, I discovered that none of the images of my feed would display in the program, and again when I contacted support they could find no issue at their end.

I have followed advice and: - cleared my cache and cookies - disabled extensions one by one - scanned my machine for malware.

Any advice would be much appreciated.

cannot log in to my Bank of Montreal online banking!!!

I've used Firefox for years, and for years I daily do my online banking.

Now all of a sudden, without any warning I cannot log into my bank account. I've tried clearing history, etc. I've tried the about:config change...

I can log in fine with Microsoft Edge.

My wife uses Firefox and she can log into the bank. I suspect that is because Firefox has not updated on her computer.

This is maddening, to put it mildly.

Even though I'm in the UK I was previously able to use the form auto fill function by changing the extensions.formautofill.available preference from "detect" to "on" however I updated to Firefox 83.0 and it reverted to "detect" and I am now unable to save any changes to it becasue it has always reverted to "detect" when I restart Firefox.

Form auto fill is such a simple and useful function that really needs to be available, Chrome has had it working for years.

Here is the crash info. Recently, usually when scrolling through sites, my tabs would crash unexpectedly. This is a brand-new laptop that I have had for a little over a week now. Any help would be greatly appreciated.

Crash Reason: EXCEPTION_ACCESS_VIOLATION_READ

Hello Community

Do hope someone can help?

Have tried all suggestions in Support area on topic: Lost/Recover Bookmarks. Also spoke to Windows Support and was told to call Mozilla Firefox Technical Support. I've been unable to find a number.

I had a Windows update around the same time as a Firefox update, May/June, only realised all saved bookmarks prior to June 2020 have disappeared. This has never happened before.

Urgently need to find out if there's a method of retrievel or have it confirmed that all of these very important bookmarks are permanently lost.

Thank you in advance

How fix this. Have googled the problem and tried all proffered solutions. No change. Others seem to have had similar problem, mentioning certificates, but got no help from Mozilla, that I saw. I have put the little jigsaw icon o the search bar, to no avail. Am deadended.

Hi folks. I know this is an easy question for you has me baffled. My old computer (Windows-7) has Firefox configured to automatically start my AOL account. But.......I can't recall the settings to make my new PC (Windows 10-Pro) do the same thing. Any ideas/suggestions welcome. Thanks Crady Adams

Strangest quirk happened recently. When I scroll down a Fox News article to the reader's comments, half of the comments are embedded with question marks etc. that make them unreadable. Not the end of the world but a little bothersome. When I use Microsoft Edge or Explorer this problem does not occur so it must be the Firefox browser. I am running the most recent #83 Firefox browser. Thanks for any help.

I was asked to update my firefox browser now I have no passwords my sites are not remembering me by password, my bookmarks are gone. my history is gone my auto fill is gone why?

Can I turn off the "control media playback via hardware media keys on a keyboard or headset or virtual media control interface" function? (Firefox 81.0, Windows 10)

I can browse the entirety of the internet but for the last week as soon as I click enter for the Infowars website the browser immediately crashes. Why is this happening why am I being blocked from accessing this page?

I started having problems with YouTube recently and I think it is a Firefox issue.

I am running version 82.0.3 (64-bit) and when I log into YouTube, the Home page is not displaying all the content.

I have attached severl screenshots and you can see the problem as follows:

Image Sign In 1 shows the YouTube home page before signing in. Image Sign In 2 shows the YouTube home page after I have signed in using my Google account and you can see at the top right of the screen that my Google Account avatar (Darth) is showing. However, a lot of the content, e.g. Watch Later, Classics and My Subscriptions which are user related are all missing and if you compare this image to Image Sign In Chrome you can see that Chrome is showing everything and works correctly.

I tried this on Edge as well and it works all okay, the same as Chrome, so that is why I think there is an issue with Firefox.

Also, on the left side in the middle in Image Sign In 1 and Image Sign In 2 you can see a blue Sign In box with the words "Sign in to like videos, comment and subscribe." If you select this option you get an error which is in Image YouTube Sign In Error so I don't know if this is related to my problem but I thought it may help highlight what the problem is.

Any confirmation that it's a Firefox issue or any solutions to what is causing it would be appreciated.

Thanks.

Hey guys,

Has anybody seen this?

As of the last few days, Firefox is starting to show jobs at Glassdoor like the image sent here, as per Glassdoor I have cleared the cache and cookies, but it still shows it like this, they also suggested to use another browser, which I did and they don't show it the same way, I don't know if this is a bug in Firefox or a problem in Glassdoor's code, but it's pretty annoying.

Thanks,

I'm running Firefox 83.0 on Windows 10. In Outlook (Office 365) if I right click in a text field, wanting to switch the language for proofing the text, there is no Language item on the menu (see image). I have the English and French dictionaries and language packs installed. It shows up in other applications (e.g. this website), but not in Outlook. This used to work...

Par défaut, dans about:config, reader.parse-on-load.enabled est sur "false". Si je le mets sur "true", il revient sur false après redémarrage de Firefox. Comment faire pour qu'il reste sur "true" ? Merci

Does someone know how the css code is for remove all Bookmarks Toolbar context menus. I added two images where you can see which context menus. Sorry for asking this question but i've searched two days and found nothing about.

I use Firex 83

Thank you.

I think I have a bug to report:

When I browse a website with an embedded PDF viewer (must be a Firefox default viewer because I haven't installed any other plug-ins), a notification bar on top of the website (right under the bookmark bar) pops up saying (translated from German): [Icon: ?] The PDF-document is not displayed correctly. [Button: "view with other app"] [Button: "x" for closing the bar].

The PDF viewer works, so the error seems unneccessary, but what really bothers me is that the bar can't be closed. Clicking the X-button on the very right doesn't work - the bar frozen until I restart the browser or close the tab. This problem exists already since summer, so at least for 2 or more updates.
