How can I completely remove the tab bar and regain 3/4 of an inch of screen space. It would be nice if Mozilla would just have a on/off button for it. I've tried creating a folder called Chrome within my Firefox Profile folder. I then created a text file within that folder and named it userChrome.css. I put this string in the text file #tabbrowser-tabs { visibility: collapse !important; } This did not work, does anyone know the best method for getting rid of the annoying tab bar?

Thank you

Firefox was working well on HTTP websites until a few days ago, but now HTTPS-Only Mode seems to be permanent. Despite changing settings to 'Don’t enable HTTPS-Only Mode', when HTTP sites are selected I get the same message as for 'HTTPS-Only Mode'. Also, if I select 'Enable HTTPS-Only Mode in all windows' and add exceptions, I get the same result.

I have been using Firefox and GoToMeeting for years, suddenly this month (July 2023) I get the following message when I try to open a GoToMeeting session”

“Sorry, this browser isn’t supported. Join in your browser by opening the link below in Google Chrome or Microsoft Edge.”

I don’t want to use either of those browsers.

What can I do to keep both Firefox and GoToMeeting?

I had a personal certificate installed in Firefox and it was working well. It expired, so I got a new one from the same provider. Both appear in Firefox under "Privacy & Security" -> Certificates -> View Certificates... The previous one is not valid any more, and every time I try to access some page with a certificate, it uses the old one. So I tried to delete the old one. Nothing has worked so far. Doing the straightforward way of selecting it in the Certificate Manager and deleting it makes the certificate disappear from the manager menu, but if I enter the certificate manager again, it is there again. I tried to delete both certificates, same issue, both reaper in the manager. I tried to delete them, close firefox, delete cert9.db, cert8.db and key4.db and nothing. Only thing left is delete my current firefox profile and start again... Any other idea or something that I might delete before to solve this?

Every time I go to Fox News, the video at the top of the page drops to the lower right-hand corner. It's an annoyance I've been searching for a way to eliminate. I have pop-ups blocked in preferences and I have a couple of different pop-up blockers, but nothing seems to work. I'm currently using Firefox 114b.09 on a Mac Desktop.

Hi Firefox We work in a government institution and we use Firefox because it is a unique, fast and safe program. We thank you for your efforts to develop the browser But we encountered a problem with the new update while printing the PDF files. It was showing us the option to print in portrait or landscape format, and when you updated version 14, this option no longer appeared. Where we deleted the new program, installed the older version, and stopped the update We trust you to solve the problem in the next update, and we ask you to give the matter importance

When using the Export Logins feature to create a .csv file, the last few fields don't seem to translate into any known date-stamp format in Excel. The data seems to have relative chronological value, but I can't make sense of it in a spreadsheet.

Can a developer check this and modify the output of those fields so it's more compatible?

Example:

 Header             Cell data
 ----------------------------

timeCreated 1675178753239 timeLastUsed 1684763722184 timePasswordChanged 1675178753239

On Google Docs, the very useful shortcut "Alt+/" for executing menu actions by name exists, similar M-x in Emacs or Ctrl+Shift+A in PyCharm or Ctrl+Shift+P in VS Code.

On a German keyboard, there is no "/" key. In Chrome the hotkey "Alt+#" works instead. In Firefox, it does not.

This hotkey is particularly important, because it gives quick access to menu actions, that have no hotkey assigned, or for which the hotkey does not work on the current layout.

Is there something I can do to make it work?

Note. Based on what I know, I cannot tell if this is an issue with Firefox not sending the Alt+# key correctly, a special feature of Chrome that isn't present in Firefox, or a cross-browser compatibility issue of Google Docs, that should be blamed on Google Docs and not Firefox.

Firefox 114.0.2 (64-bit), running on Open Suse 15.3, 64 bit.

Why is there not a simple means to take a link and pin it as a tile on my home page? I've expanded the number of rows displayed which as an odd history of my browsing, yet the latest links I've visited are not there - meaning the link to the location I would like to pin. Seriously, the entries in the rows (other than previously pinned links) is a hodgepodge. It might be useful if there was some evident logic to the items included. It is disappointing the number of times this question has been posed and the "answer" is to display more rows. Similarly disappointing - an old knowledge base article that says to click the 3 dot icon next to address bar for Firefox on android - would have been handy had such a control appeared in the latest version of Firefox I'm running on my Mac.

Firefox 114 introduced hidden support for nvidia video super resolution. In about:config you can enable preference gfx.webrender.super-resolution.nvidia to make it work. However I see 0 difference on all videos on all pages. I have everything in nvidia control panel set correctly (VSR enabled and set to 4/4 quality).

Tried to find more info online and someone on reddit complained that it worked before but it stopped working with latest firefox beta (probably before final 114 release): https://www.reddit.com/r/firefox/comments/13duluz/nvidia_video_super_resolution_comes_to_firefox/

I tried using logic too - if this pref is related to webrenderer in its name maybe it is not working because I am not using webrenderer? However I checked about:support and in section graphics->composition I have "webrenderer" so it seems I am using it, but its VSR feature is not working at all.

What is the code to remove that new menu Search Bookmarks in new firefox 114?

I already remove all the previous "bookmark all kind of type menu" in userchrome.css

I have lots of bookmarks, which I organise into folders and subfolders. In the last month or so, Firefox will no longer save them to the folder I specify from the pull-down menu when saving but just adds them to the general bookmarks menu. To sort my bookmarks, I have to go into Manage Bookmarks and move them manually. What's happened?

I tried to log in to a website that requires access to my location. I'm using Firefox 114.02 on an iMac running Monterey 12.6.7. I was able to get in to Firefox's Location settings and now have the website listed with "Allow" noted. This was not enough, and for some time I didn't understand why. Then I discovered the Mac's System Preferences' Security and Privacy section, where Location Services are one category under Privacy. Selecting Location Services brings up a list of apps that are allowed to provide location information. For some reason, other browsers are on the list and can be turned on or off, but Firefox is not on the list of apps that can be selected as permitted. Am I missing something here? I can't find any way to add apps to the list so that they can actually be selected. Any advice?

I've been having a weird issue with my text glitching only in my Firefox browser. Initially I thought it might be my monitor but then I realized the issue only presents itself in my Firefox browser. Literally no other program is affected.

I've done a reset, I've uninstalled and done a clean install, I've deleted all Firefox files and re-downloaded the browser. The issue immediately pops up again.

i've tried toggling media.hardwaremediakeys off and pressing the media keys to no avail, they don't seem to have any effect when it's enabled or disabled. the keys work on other applications like VLC media player, though! and I can see that the media is being detected from firefox, too, as it appears in media player widgets i have on my plasma desktop. it seems to be only the physical keys that aren't working, because i can press buttons on the widgets to control media playing in firefox.

I'm developing a PHP Symfony based website powered by nginx-full 1.18.0-6ubuntu14.4, one of the functions is to allow people to download a PDF invoice.

When it fails Firefox shows an alert "Downloading (Failed) The browser application closed unexpectedly."

On my linux desktop; when I use Chromium 114.0.5735.198 this functions works 100% of the time. when I use Firefox 114.0.2 (64-bit) the PDF download only works ONCE after that the download never completes and I'm left with a partial/corrupted 75.7KiB file named filename.Br-neZWO.pdf.part etc.

I have discovered that if I clear the firefox cache I can perform one successful download again. or I can restart Nginx and again Firefox will perform one successful download again.

I've tried altering many Nginx settings, cache, gzip, sendfile etc with no effect. It might be Nginx related but it does not effect Chrome at all which is why I've started this ticket.

Any help in debugging this would be greatly appreciated.

Hello I want to disable/hide or at leas make smaller the GIANT "detail" bar that shows up on the history manager and difficults reading trough the history. There seems to be no options available in the toolbar and can't find any on about:config either. Perhaps there's a key I can add in about:config to change this?

Thank you

I view a page, for example, news.yahoo.com. I usually scroll down a way, possibly to the bottom. I step away, and when I come back I want to refresh the page. Up until about two weeks ago, when I press F5 to refresh the page, it would automatically scroll back to the top of the page. Now it seems to go to (maybe) a percentage of the page based on where it was last scrolled. I then have to manually scroll back to the top to see the latest headlines. Was Firefox behavior changed? Is there a setting to control page refresh behavior?
