Firefox Community Forum

I am on Linux Mint 21.2, and I just updated Firefox (141.0). Now, the bookmarks bar, toolbar, and the tabs (everything above the displayed page), as well as the menu, bookmarks menu, and sidebar, are in light mode even though I have dark mode set (They were dark before the update). I tried playing with the Dark Mode settings to no avail. My system is set to dark mode in general. Are others experiencing this? Is there some sort of fix?

This is the link. I can't send animated images as the text is too small, so I'll describe it instead. It's so hard as a loyal fan, I'm crying.https://www.bilibili.com/bold text。There is a bug. Why does the Bilibili website not display the corresponding screen when I try to move to it? Speed playback cannot be used at all, and there’s also the issue of not being able to use fullscreen on Firefox. Are you forcing me to use another browser?

Hello. I have a problem with turning off google safesearch. I'm 28 years old so it's not a problem with google acc. I have same firefox on pc and on laptop. On pc and on smarthphone it's easily turning off and if i'm using edge or chrome on laptop it's also turned off, but if i'm using firefox exactly on google it's always turned on no matter what i'm do. Just in case, if i'm using for example bing search in firefox it's also turned off, likely it's always turned when i'm using google with combination in firefox. Methods that I already tried: 1) Turned off in computer settings (not worked) 2) Reinstalled browser (not worked) 3) Checked in my wifi settings (not worked) 4) Updated everything (not worked) Waiting for your help.

I currently can't stream anything, and this keep getting this message: Widevine Content Decryption Module provided by Google Inc. will be installed shortly,but it never installs.

I have a macbook air and am currently running macOS Sequoia version 15.0.1.

I tried uninstalling and reinstalling, removing extensions, clearing cache and data, unchecking and then checking back again the reproduce drm protected content but nothing has worked.

I have the most recent update and have been excited about tab groups, but it's still not working on mine. I thought the update would be available to all as of May 6, 2025. Is this happening to anyone else?

So I understand this: https://support.mozilla.org/en-US/kb/xframe-neterror-page and the reason it exists, but I need to find a way to turn it off because it's literally blocking me from accessing the Library of Congress webpage inside the same browser for my job. It's not a malicious site, but I can't figure out how to tell Firefox to stop blocking it as if it was a malicious site.

Help.

I updated to version 133 today and was confronted with the vertical tab bar. I did not ask for this or want it, and now I can't get rid of the side bar, in fact I seem to have just made it worse / wider. How can I get rid of this (and block it) It is just taling up space on my screen. Please help.

Hi! I'm using Firefox 126.0 on Fedora 39.

Pages from Amazon.co.uk load very slowly, incompletely, or not at all. All other Web sites are fine.

I had a couple of certificate-related errors saying that the identity of the site couldn't be verified, but I can't reproduce the problem, so I can't quote the exact wording, I'm afraid.

The same Amazon pages load properly in Chrome on the same machine, and they load properly in Firefox in a VM on the same machine. That tells me network connectivity must be fine.

I've tried disabling all extensions, reverting to the default theme, running in Troubleshoot Mode, clearing cookies and site data, clearing the startup cache, disabling hardware acceleration, and creating a new profile. The new profile helps slightly, in that it loads more of the page before getting stuck. Nothing else helps at all.

I'd prefer not to refresh Firefox if I can avoid it, because I don't want to lose all my plugins and settings. This installation is five years old. Besides, a new profile didn't fix the problem.

What's the next thing to try? I'd really appreciate any ideas.

AI "summaries" or "explanations" have been popping up in front of actual useful text that I want to read. How do I disable this AI summarizer or turn it off? If this removes an AI chatbot, even better.

Hello. In the past two days I lose my tabs when I shut down Firefox. I used to be fine using the X at the top right and when I restarted the browser, all my tabs would still be there. Then they started going missing, so I started using the menu option to exit the browser. The tabs still went missing.

Then I noticed the square icon button on the extreme left and have discovered that Firefox has different windows, and that one of them (see attached image) has all my tabs in it, while the current window does not.

I cannot change Window 2 to be the current window. There is no obvious function on the page, nothing in settings and google is useless - I just get pages of discussion of how to tab between different apps on the desktop.

How do I make Window 2 the current window? See image.

Thank you

My Firefox Browser on (Windows 11) updated on 23rd March 2024. Now my History and Bookmarks have been deleted (but not cookies for some reason). yes, it is my correct profile as I checked the dates and also double checked it against a backup I made 2 weeks ago.

Have included an image of my 'more troubleshooting information' details - I'm sure this is supposed to have more data on the page?

If there is no way to recover my hisotry and bookmarks, I see there in my profile folder is a 'bookmarksbackup' folder which contains .jsonlz4 files, one of which was saved on the 21st March 2024. I know book marks are .json files, can anyone tell me how to turn a .jsonlz4 file to a .json?

[Oh, I pressed to add here my 'troubleshooting information' as directed by this forum page and it said it couldn't automatically do it, and when I pressed 'manual', it opened that over this page and so when I pressed 'back' it had naturally deleted this post so I've had to retype everything from memory, thanks so much Mozilla for that. How about a warning that this will happen?]

I have Firefox Browser version 112.0.1 (64-bit). Firefox says that there is a new update. In order to install the new update it is required to have Administrator privileges in the computer. Until now, to update Firefow, Administrator privileges were not required.

In Firefox, and only in Firefox, I get 'Failed to verify your identity' on these sites. I have updated MacOS and Firefox, rebooted, tried a different DNS, and disabled all of my extensions. With extensions disabled I don't get the error, but the login site won't accept my login at all. See the attached image. I can't think of anything else to try.

I tried to log on this morning to my mail and get this link" https://guce.yahoo.com/consent?brandType" with a pop up page "oops something went wrong"

all searches I have done to try and resolve seem to be 2019 or older with the 2024 being locked.

I type in yahoo.com, do a search yahoo, they all come up the same message. anything yahoo related I cannot load. and get this same message.

I run malware byte and Ccleaner neither solved this issue

I use Microsoft edge and have no issues.

thank you

I have tried watching videos through chrome and other browsers by searching something via duck duck go and watching that video on duck duck go, and it works on other browser so it must be specific to firefox.

Whenever I try to watch a video, in the drop down bar firefox select to mute audio for some reason. I then select 'allow audio and video' and refresh the page but the video is still muted for some reason. This also happens when I try to use other video sites. This has only started to happen recently in the past two days (and yes I am updated to the latest version of firefox).

An hour ago I had all of my Firefox bookmarks. Ten years of meticulously filed and regularly culled references that I use multiple times daily. I rarely log out of Firefox sync, so that I can keep them up to date.

I now have no bookmarks and no tags.

For some context, two things just happened simultaneously. So, I'm not entirely sure which is the culprit.

1) Firefox just updated and I rebooted my computer.

2) Norton 360 updated sometime in the past two days. I attempted to familiarise myself with the new interface. Foolishly, given the track record of Norton-360-for-breaking-your-games, I ran the disc cleanup, which recommended I remove approximately 400 Mb of data. Norton stated this data was temporary files. If they were indeed my bookmark history, nowhere did Norton indicate they were bookmarks. Also, never have I encountered a disc cleanup that wholesale wipes bookmarks. I do hope Norton is not the culprit and this is just a glitch, because if this were due to Norton having no safety net for deleting an entire library of bookmarks - and they can't help me restore them - then that will be the final nail in the coffin for me doing business with Norton.

The suggestion to go to Import and Backup in Firefox, then click Restore, offers only the option of Choose file... - and then launches nothing.

Currently, I'm seeking any means of restoring my bookmarks. Any help would be appreciated.

I had presumed that I was taking reasonable measures through my Firefox Sync settings to protect my bookmarks and ensure they could be restored in the event of accidents. If these bookmarks are permanently lost, the amount of work I've just lost is quite the blow.

Edit No. 01: After writing this, my Bookmarks Toolbar is also now empty. Perhaps it had wiped earlier, but was merely waiting for a refresh to take effect.

Edit No. 02: Also, it seems I am unable to create any new bookmarks. I shall read the help suggestions relating to that now, to see if it's a relevant issue.

Hi

OK so I was having some issues with firefox where I had to reinstall it and this did in fact resolve the issues I was having.

Problem I have is this though when I reinstalled it I first backed up my chrome folder which had all my custom CSS to move the tabs to the bottom of the header area and when I then reinstalled FF I then copied the folder back into my profile folder using the More Info under the help menu to make sure I was in fact in the right profile folder.

Problem is the code isn't moving the tabs and I seem to remember some issues with this the last time we had to fix FF that something had changed with the Chrome folders and such.

So what do I need to do to get my tabs back on the bottom again as I hate them up top!

Version: 128.0.3

Thanks!

Hi,

Is this new feature? Once I click on link with middle mouse button, that tab is opened and switched to it. Previous firefox versions only opened tab and thats it. It is very frustrating. I want open multiple tabs and then view those tabs. Now I have to, suppose I have 5 links listed in webpage:

I middle mouse 1st link Then I have to return to my previous page I middle mouse 2nd link Then I have to return to my previous page I middle mouse 3rd link Then I have to return to my previous page I middle mouse 4th link Then I have to return to my previous page I middle mouse 5th link Then I have to return to my previous page

If it is new DEFAULT, then please make ant option to switch back in about:config, thanks!
