Firefox doesn't show sent messages in Gmail. Neither individual sent messages nor conversations that include sent messages. The message lists display fine, but when I try to open a message / conversation it only shows a blank page. Currently the version of Firefox on this computer is 83.0 (64-bit), although the problem occurs since the most recent versions. It only happens with Gmail. Yahoo! and AIM work fine. Doesn't happen in Chrome or Edge

If I use my touch monitor when a video player is full screen, the full screen Firefox window turns grey and becomes unresponsive to mouse and touch input. I can exit full screen with Esc or F but the problem persists in full screen mode until I restart Firefox. Picture attached is my monitor when Firefox is in full screen mode.

SEC_ERROR_UNKNOWN_ISSUER for Google and Youtube

I am getting a certification issue when trying to visit 2 specific sites which are some of the most visited sites in the web: https://www.google.com and https://www.youtube.com

The error it shows when trying to visit these 2 pages, is SEC_ERROR_UNKNOWN_ISSUER.

I have tried to troubleshoot it and follow the solutions recommended at: https://support.mozilla.org/en-US/kb/error-codes-secure-websites#w_the-error-occurs-on-multiple-secure-sites

however none of the solutions described in this guide worked to solve my problem.

In that guide, one of the suggested solutions is to scan my system for any malware. I used the following: Windows Defender Maleware Bytes AntiMalware Karpersky TDSSkiller however the results are all clean.

In the guide, it suggested that I check the clock as well. The system clock however is synchronized.

Last, I have resetted Firefox Profile but this didnt fix the issue either.

I shall note that the issue appeared yesterday and so far nothing helped fixing it. Not even the system restarts.

The issue about visiting these two sites, is limited only to Firefox.

I can access https://www.google.com and https://www.youtube.com without problems using Google Chrome and the Opera Browser.

Also, Google Mail and Google Translate work fine on Firefox. These two sites can be accessed with Firefox without causing any SEC_ERROR_UNKNOWN_ISSUER errors.

I want to change text encoding so it defaults to Unicode. If I use the [alt] key then the View tab I can change it from Western but it reverts back after closing the page. Sometimes that does not work because the Text Encoding option in the View tab is greyed out. The About Firefox window says I am up to date with 83.0 (64bit).

Good Morning

Today I had to repair Firefox and after restarting, I felt a strange scrolling sensation, it was not the normal Firefox scrolling, I even thought I had openend the wrong browser...so I went check about:config , and found some values where changed as new default values:

general.smoothScroll.mouseWheel.durationMaxMS 200 general.smoothScroll.mouseWheel.durationMinMS 50

I tought it was me the problem so I installed an older version of Firefox (80.0) in order to compare, and found a normal scrolling and those values:

general.smoothScroll.mouseWheel.durationMaxMS 400 general.smoothScroll.mouseWheel.durationMinMS 200

I think this is a mistake from devs, if i wanted to have horrible scrolling, I could just use Edge instead of Firefox, could you please bring the original scrolling back to Firefox?

Thanks

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 hate the "This time, search with" in the URL bar. When I want to search, I use the Search bar for that. I don't need extra icons that I'm not going to use taking up space in the URL bar. I've seen it suggested that they can be removed in the Search options page. But when I've tried that, it also removes them from the Search bar.

Here's what I want: for the URL bar to only have space for a URL, no "This time, search with" nonsense, but the Search bar left completely intact, with all the search engines I use.

I realise that Firefox uses up a lot of Memory (particularly as it tries to run each Tab separately). However, my Firefox seems to keep increasing its usage!

I can start with a number of Tabs open & (after refreshing each Tab - to ensure it is "lice" & "active") I will get (according to Windows Task Manager) about 1,300MB in use.

Without opening up any more Tabs & without trying to run any Web-Based Videos, over a period of a few hours it will increase & increase & increase - perhaps getting up to 4,000MB!

I've cross checked with "about:performance" (to open FF's own Task Manager), to show the individual Tab usage, & that NEVER totals up to anywhere near the figures shown by the Windows Task Manager!!

Obviously, my FF is fully up to date!

Any comments!

Hey!

First time I get that, I usually lose my tabs due to my mistake but this morning after starting my PC all the tabs were gone with no option to restore or any error message. I backed up my previous session json and other files by hand but every time i copy it back into my profile folder and rename it sessionstore.jsonlz4 it just gets deleted after I open firefox and none of my old tabs get loaded. I scrounged the files before and saw that they contain my lost tabs, I just can't seem to restore them. I tried reinstalling firefox too but that didn't help.

Did the restore system change or is the backup corrupt ? Thanks!

Fred

After updating to FF 83.0 something has changed in font rendering. Another update breaks something for me and another silence in changelog.

When hardware acceleration is enabled in firefox settings I observe that fonts which are overlayed on youtube videos have ugly chromatic aberration effect around them and they are much thinner than they should be. When I disable hardware acceleration they are fine - they look the same as on different browsers, for example Brave.

Is there any way to fix font rendering without need to disable hardware acceleration?

I had to reinstall Ubuntu 20.04 because I removed vital Python 2 and 3 and it broke. Before doing this I was logged into my Firefox profile and should have had my bookmarks and extensions synced. I do not see any reason why this would not be the case. However, after my reinstall of Ubuntu and logging into Firefox profile all of my bookmarks and extensions are gone. I tried checking around Firefox and it only shows bookmarks and extensions from after my reinstall. I have not performed a backup since I reinstalled Ubuntu, but those bookmarks are there. So I don't understand why I can't find my old bookmarks and extensions from before my Ubuntu issue, because I was logged into my Firefox account. My Firefox account information should have been saved to my account not my computer anyway. Please help me I had a lot of important bookmarks on there, but can't remember all of them.

Many sites have videos playing when I open the page. If I just ignore the video and scroll down without explicitly stopping the video, I get a popup window playing the video. Apparently the popup blocker doesn't consider this to be a popup. Is there any way to kill this annoying behavior?

Since the last (?) update, sometime in the spring months this year, Firefox has not been able to display website fonts correctly. Often times part of the fonts turn to question marks, and the problem just turned even worse: even sites that I use regulary turned to complete mess – ALL TEXT. What the hell is wrong?

And NO, preference settings have no effect whatsoever.

I have two defined log-in users on my custom-built Windows 7 Pro desktop. On the account I use, the last entry in the Page Actions menu the "Take a Screenshot" option lo longer appears at the bottom of the menu. However, on the other account the "Take a Screenshot" option does appear? I can find nothing in the Firefox 83.0 "Options" or "Customize" menu that can affect the Page Actions menu in any way, nor can I see any apparent difference in any other option in effect between the two user accounts' settings? Any ideas on how I can get my "Take a Screenshot option back, short of uninstalling Firefox from the computer and re-installing, wiping out both users' bookmarks, add-ons, etc.? Thanks.
