Firefox Support Forum

I use firefox since I go to college. When I got some problems, I try to check firefox use what to pick folder? I use Manjaro Plasma. I find chrominum use kdialog. But firefox looks not though both use gtk3 as UI

Firefox choose folder got wrong when use a USB HDD

i have rebooted, Firefox is my default browser on Linux, and i can only bring up Gmail - no other sites, not even my bookmarks. just started today..... no other changes, unless accidentally

Hi, Could someone tells me how to deactivate the startup popup upon each firefox start which says (translated) "thanks this is 100th version of firefox, start navigation", or is it to stay until the 1000th annniversary ? Thanks

When I restart my computer, I am logged out of all websites although I did not select settings such as "Delete cookies and site data when Firefox is closed". This only happens with reboots and not on Suspend.

I saw two similar posts but the options look like they changed name since then: https://support.mozilla.org/en-US/questions/1319622 https://support.mozilla.org/en-US/questions/1289909

I tried to apply the solutions linked there, to no avail.

This behaviour only happens on my Garuda Linux and not on Pop-os. Thus I am not sure here is the right place to ask this question.

Another strange bug which may be related is the following: if I zoom in a page (say set it at 120 percents) then go to another tab and then come back to the page I zoomed in, the zoom is reset to 100 percents.

Any help would be greatly appreciated!

I was having trouble switching and logging out of Twitter so I thought I could just clear site cookies to make it work, but I weirdly discovered "about:preferences -> Manage Data -> Remove Selected / Remove All Shown" has no effect. i.e. after clearing, when I open up manage data again, they are still there. I did not try "Clear Data" above it because I was afraid of clearing out all my logins.

I reinstalled my computer several weeks ago and current profile was directly copied from my last machine, so this might be a possible cause? Could someone be so kind to help me get remove cookies and hopefully twitter back to work? Thank you in advance.

When I select in Settings>Privacy & Security>History, that a history should never be saved and close the Settings tab, the next time I go to Settings, the option is replaced by the setting, that saves a history according to customisation and there's a check mark to always use the Private Mode. Apparently Firefox doesn't keep or save the setting. I learned from https://support.mozilla.org/de/kb/privater-modus that saving a history according to customisation with the option to always use the Private Mode enabled, is the same as never saving a history, nevertheless it should be possible to keep the setting (as the setting exists). How can I solve the problem?

My problem,using Mint20.2-MATE, with FireFox92, is that FF92 shuts down whenever I minimize FF-i.e., totally down-does NOT appear in taskbar. I know I had the same problem years ago, and it was a simple fix. However, going through the "Help" sections in FF this time was no help. thank you for any suggestions.

I got help with this from your group some weeks ago, but I had to reinstall my Ubuntu OS (linux v.20.04.4 -- using firefox) recently and can't recall the answer.

When I view a WikiSpecies list of file names (e. g., see https://species.wikimedia.org/wiki/Pentatominae), the instances which have been installed but never used should be in a different (reddish) color. I am attaching an image of a page containing a file named "Abadia" (first one on the left, just under "A") which is unused. I also am attaching an empty "Creating Abadia" which is the result of clicking on "Abadia".

Please tell me how to change the image of an unused, empty file. I recall that there were two different choices SOMEWHERE in the system, "Always" and "Never" I think: One of them forces a system-level color pattern which includes reddish unused items; the other allows the used to program arbitrary displays such as the above (typical example from the dconf editor is 'bg_color: #f0f1f2; selected_bg_color: #023C88', but this editor does not change the appearance of a file instance.

Whenever I use web-applications that use WebGL or anything similar, they are always distorted. And yes, I have tried disabling Performance Settings, but that only slightly helped.

I have moved from Centos Linux to Rocky Linux and could not play Perron FM on onlineradiobox.com whereas I could on an Ubuntu Linux machine. It turned out I had to install ffmpeg (dnf ffmpeg) on the OS to support the right codec. The error was (in Firefox developer view, F12): HTTP “Content-Type” of “audio/aac” is not supported. Load of media resource https://onlineradiobox.com/json/za/perronfm/play?platform=web failed. Hope this helps someone.

I am frequently needing to clear the Cached web content, when doing development work on a website. I always need to remember to remove the check mark from the Cookies box. However, I sometimes forget and loose dozens of log-in cookies and need to reset them, which is a big pain.

I was unable to find anything in the Firefox Advance Configuration settings. In Chromium and Chrome browsers, only the Cached images and files box is set with a check mark. If I cannot change the default for Cookies, this is reason enough for me to switch browsers, despite using Firefox for many years.

This question was asked, but the answer is outdated. This option no longer exists.

I am using version 116.0 for Arch Linux.

When you open a link from the sidebar while holding ctrl, firefox opens it in a new tab and switches to it immediately; whereas when you click a link from a webpage with ctrl, it does not switch to the new tab (unless you hold shift as well, or check "When you open a link, image or media in a new tab, switch to it immediately" in settings > general > tabs). I would like if firefox does not automatically switch to opened links from the sidebar (history, bookmark, etc.), when I open them with ctrl? (I know I can hold shift to do that, but I was wondering if there might be a preference in about:config to change the reverse this behaviour for sidebars)

Thanks, Ibr.

The proton changes might make for a better smartphone experience, but it really trashes operations on computers. In case you are wondering why firefox's share of the browser market continues to slide, upgrades like "proton" are the main reason.

i am currently working in Kubuntu 20.04 with Firefox 95.0 (64-bit). I'm not sure how it started but slowly whenever i close a conference (closing a conference includes exiting audio or closing the tab entirely. and this has happened since about a weeks or so), such as google meet and all, Firefox crashes and opens the crash reporter or something. i have reported this several times but I'm not really seeing any fix or causes. if it helps, here is the link for the crash report - One of the crashes i have reported i have two add-on installed- Tab Auto Refresh and Ghostery – Privacy Ad Blocker Do let me know if you require any other information regarding this.

Cannot get rented/paid Youtube or Netflix video to run. Message "! Sorry, there was an error licensing this video" pops up onYoutube screen every time when hitting play button. "Free" Youtube videos work just fine, paid content gets this message. Have firefox-9.5.0.2.ta.bz2, use Linux updated software. Followed all previous suggested Support, cannot seem to find fixes that included DRM, Safemode switch, etc. Thanks for previous help, still stuck... anymore ideas appreciated. Also, difference between running "normal and beta", please explain, and how to know "differences?"
