Firefox Support Forum

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.

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.

Hello, I would like to know how to remove 'other bookmarks' folder from the right side of bookmark toolbar that showed up suddenly on my browser, it's right after the arrows to show more bookmarks. I can't seem to find a way to delete this.

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

I hav been using my Gmail in Firefox with no problem until about 3 days ago. Now when I try to sign in to my account I get a pop up window which states “This browser or app may not be secure. Try using a different browser. Etc.”

I have tried another browser (chrome) and Gmail works fine, but I like working in Firefox. But at this rate I may dump Firefox and go to another browser.

I have looked through the other support group questions and solutions. I have tried them all and nothing is resolved. Clearing cache, clearing cookies, using a private window, managing data, using forget about this site, generating a new profile, disabling extensions, loading in safe mode, etc.

I have Firefox version 83.0 (64 bit). My operating system is windows 7.

Any other suggestions?

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.

Recently, I had to change my username at my bank's website because somebody was trying a brute force attack on my password. Now, the site still shows my old username, although I've gone to my Saved Logons in Preference and removed all logons for that site except for the correct one. I have to delete the old username from the typing box every time I log in there, after which I can select the correct (and only) saved username/password.

Friends, I use FF extensively and prefer not to change but it's been very annoying as of late.

Running v83. Even downgraded to v82 and it worked for some minutes but now it's back to same behavior. [struggle to download to 82 is here: https://rezamusic.yolasite.com/technical-tips.php]

If you google "squeeze lemon" for example -- on my Chrome it shows images and a list of drop down subjects "people also ask".

On Firefox, the pictures don't show -- and drop downs are frozen (don't work). Also on other sites that have a Captcha, Firefox just doesn't work. Seems same problem with 82. Help!

Images are from Chrome -- and last one from Firefox

Under EXCEPTIONS I had to ALLOW certain websites. Then I decided to experiment and see what ALLOWED for SESSION really does.

Neither the entries for websites I allowed for a session were deleted from the list of exceptions, nor the cookies saved by these websites were deleted even when I closed the browser.

I do not see the difference in terms of what happens between selecting Allow vs. Allow for session.

Could someone who knows please explain or point me to the place that explains the difference and how this works?

Thanks.

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?

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.

Hi, I am an experienced firefox user for more than 2-3 years. But i recently need NPAPI plugins to do certain works. I learned that i need 32 bit to do that. I already have 64 bit. Now my question is can i have 32 and 64 bit at the same time? If i can't, then can i migrate my data from 64 bit to 32 without any data loss? i am free to give further info if needed. Thank You!

Hey there,

I have the following issue with Firefox, is this maybe something I should report to the Ubuntu support or directly to Bugzilla?

Steps to reproduce: ---

1. Open Firefox
2. Go to a page that contains an embedded video that is not playing automatically, e.g. https://www.rottentomatoes.com/m/sound_of_metal
3. Do not play the video

Environment --- User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:83.0) Gecko/20100101 Firefox/83.0 Firefox version: 83.0 (64-bit) pulseaudio version: 13.99.2 OS: Ubuntu 20.10 64-bit Gnome version: 3.38.1 Windowing system: Wayland CPU: Intel® Core™ i7-8565U CPU @ 1.80GHz × 8 RAM: 15,5 GiB GPU: Mesa Intel® UHD Graphics 620 (WHL GT2)

Actual results --- pulseaudio process is spawned and rapidly becomes the most CPU consuming process on my machine (especially after a few seconds, when the Web Content ones start to cool down). Even though no sound is actually played! When switching to another tab with no embedded video, pulseaudio keeps overloading the CPU. This only stops after closing Firefox.

Expected results --- I'm not sure this is what should be expected, but I'll give it a shot:

• pulseaudio process should only be spawned when actually playing a media that requires audio
• pulseaudio should not be the #1 CPU consuming process
• pulseaudio process should at the very least not massively use CPU when no sound is playing

Firefox won't stay downloaded to my computer. I am having to download it multiple times, especially if my computer has updates.

On a separate note, when it does actually stay on my computer over night, it never keeps me signed in to my Firefox account. I have to log in to it daily to have my bookmarks and passwords.

Also, it never remembers the theme I have picked for it. I would love some advice on how to fix this.

I've read through a ton of articles, and I can't seem to find a fix.

When I access Task Manager from the Firefox menu or just type about:performance the screen comes up, but it only shows information for Task Manager itself (low impact) but doesn't show information about open tabs / websites or add-ons. I was trying to use it to see if one of my open tabs was impacting browser performance. I have the latest version of Firefox.

When Picture-In-Picture mode first release, the size of the video was respective to the video's resolution, the window would increase in size the large the resolution and decrease the smaller. This allowed the window to be customizable in size. Now, for me at least, every picture-in-picture video is a tiny window. Is there a way to tweak and increase the size of the video like before?

I know how to bookmark a page- what I want to know is how to restore the bookmark star in the address bar (I accidentally removed it). I KNOW that you can bookmark a page by clicking the 3 dots at the end of the address bar and using the drop down menu, etc, or key commands.

BUT- I want to RESTORE the star that easily and quickly allowed you to bookmark a page. All other answers to this same question seem to only tell people alternate ways to bookmark a page. I don't need that. I need to know how to restore bookmark star to address bar. Thanks! my firefox ver is 84.0.1 64bit
