Firefox Support Forum

I have Firefox 107.0b5 (64-bits) Snap for Ubuntu canonical-002 - 1.0 I use Ubuntu Mainline to update to newer kernels. Never had any problem doing that. I am now on 5.19.15. But when I upgrade to kernel 6 (which is now at 6.0.5) Firefox tabs crash. Reloading doesn't help. Each new tab I open gives the same crash message. I have to restart to get Firefox going again. So I removed kernel 6 and reverted back to kernel 5.19 and have no problems any more. But question, what is the problem between kernel 6 and firefox? Does anybody else experience this problem?

I have no other problems with kernel 6 with other programs or hardware or whatever, only firefox tabs crash...

One of the beauties of firefox has long been that I could use the backspace bar instead of the back button to return to the previous page when browsing. Somewhere in the last updates this wonderful functionality was lost. Is there anyway I can restore this? I'm suffering from Parkinson's Disease which oftentimes makes controlling my mouse nearly impossible.

I've got about 10 bookmarks with links to support pages each about adjusting specific about:config setting to my needs. My job also requires me to change systems lots of times, from Mac to windows to Linux. Is there an easy way I can save my personal about:config changes to a file for easy import on other systems?

Thanks

As of today, I'm seeing black text on the black background of every site with a dark theme, including Google Search and Github

I'm running Firefox Developer Edition 105.0b8 on macOS 12.5.1. My macOS Appearance is set to Dark

Switching the Website Appearance config setting between Firefox Theme, System Theme, Dark, or even Light does not change the colour of the text

Hi Today I updated Firefox to version 106.0 and I can't get rid of the "arrow button" from top right (screenshot attached - near the minimize button, I marked it). The function of this button is clear for me - tabs management. But I can manage my tabs without special button for it. I want to remove it. I tried right clicking on it, but the "remove from toolbar" option is unavailable. I tried to customize toolbar, but it won't work either (I can't take it from te toolbar).

How to remove this button?

Hi, FF 89.0b2 Developer edition now contains a "fake editable" search field at the home page (the sentence contains in the class attribute so I used it here), when one start typing in it and the letters appear in the address bar.

For me personally this is partly non-intuitive partly annoying. I never met a scenario in UI of other programs, when typing in one place (where the caret is) show actual letters at another place.

Is this feature is here to stay or are there plans to to make it customizable? I used ff home page search for ages, now I installed a new tab home page extension with manually setting www.google.com in it.

Thanks

Hello, I'm currently running firefox developer edition and i'm facing a weird bug: When firefox is started, opening a web url from outside of firefox window does'nt work and display error message: "Firefox is already running but is not responding...". It expects that i close all instance of firefox instead of just opening url in a new tab.

Do you have any idea?

I'm working on version 105.0b2 with two profiles on an ubuntu 22

I am trying to add a new extension but it does not add it to the bar's right side with others. There is no direct option to do that. How do I add redux to that place?

When I try to log into my website - https://huppbrian.us/tsc-admin - with Firefox Developer 111.0b8 (64-bit), get the following error first time every time... Error: Cookies are blocked or not supported by your browser. You must enable cookies to use WordPress. If I try again without making any changes, I'm able to log in fine. I've tried playing with the protections settings, but haven't found the magic pill to fix this yet.

After updating to version 94.0b9, the program began to slow down terribly. This is especially pronounced on YouTube: you select a search, enter a request, open two or three tabs from the proposed one with a possibly useful video ... That's it! You can go to a cafe for coffee and rolls. It became impossible to use the browser.

How to roll back to the previous version of the program?

Sub.: now Firefox Developer Edition 94.0b9 for Linux

Clicking the mousewheel still works, but scrolling doesn't work. This behavior occurs on tab bar as well.

Using option "Restart with addon disabled" from about:profiles can make the mousewheel scrolling work, but manually disabled all addon and restart just won't solve it.

Is it still necessary to use both !important and @namespace url(http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul) inside userChrome?

If I copy and paste any two words or more into the search bar on the new tab it goes to google.co.uk as that is set but only searches for the phrase minus the first word. If I paste it into the address bar everything is ok. If I do the same with a one word term the search bar does nothing having "lost" that word and the address bar works fine.

Firefox crashes at startup even in safe mode. I think there was firefox update after first crash and it did not start after that. Developers version works fine.

When I right click on an image in Firefox, I've always been able to select "view image info". This is very helpful, but now it appears to be gone in latest Developer edition. Do others see the same. If so, why was it removed? It's still there in the regular version of Firefox.

Managing profiles: My Firefox since rel 89.0 crashes several times A DAY. The last time it crashed 6 times in a row then WIPED out my copy and gave me a new copy, BLANK of everything. I am no rookie to Firefox as my first version was 1.0 when I converted from Netscape Navigator long ago. The rub is PROFILES. I have too many to manage now and need to get rid of some but Moz:lla in their infinite wisdom does not put a date, what was the LAST one.... and one has to search to find the LAST profile that has your latest modification, data, etc. I am fearsome in deleting any as they do not seem to be in any order and I get a SERVE warning when trying to delete. Since the new releases crashes all the time, to do critical work I have to resort to UGH, "EDGE' until Moz://a gets a solid release and hopefully STOP TRYING TO COPY EDGE AND CHROME.

Any advise will be appreciated. [except advise to use EDGE or CHROME].

I have set Firefox Developer Edition (Windows 10 20H2 & 21H2 and Ubuntu 18.04 & 20.04 installations, always kept up to date), to use English (United Kingdom) settings in preferences. I have installed the UK Dictionary and made it the default for spellchecking. The Windows installation is also supposed to be respecting the OS regional settings. Firefox seems to be totally disregarding the settings and always giving me US as the location and US English for the spellcheck. This has been an issue for months if not years. I understand that many pages will be US biased, that is not a problem. The problems are that my country preference is being detected as US, and that I can not seem to get Firefox to actually use the UK Dictionary. I can supply additional information as required

I used Apple Migration Assistant to move the entirety of my wife's old iMac (the old computer won't accept updates, so her machine was not secure) to a new one. The migration operation appeared smooth and essentially perfect.

Somehow my Bookmarks have overwritten my wife's (years ago, I turned Synch = ON, was that it? Synch is OFF now). The bookmarks are still OK on the old computer, so how do I locate and move that info to the new machine "AND BE SURE TO GET IT RIGHT"? My wife is the family business manager, so her bookmarks are Insurance, Banking, Healthcare, etc.

I've done some searching, but there are thousands of posts, I can't wade through all of that.

Firefox Developer Edition - Developer Console is killing my productivity. It started opening in Full screen mode about a week ago and will not exit full screen. I have to F12 and exit developer console. This is a major issue because, I work with the console not docked. Docking blocks my productivity. F11 only puts it into some very weird outline mode where all I see is a rectangular grey outline on my full screen. If I click on it, it repaints the console in full screen. There is no option to drag and expand or contract. Nothing. Nada. Please help. This is my primary browser, er -was my primary browser. I'll continue to work around it until my patience is completely exhausted. Almost there now.

Sorry about the terrible markup on the screenshot. It's hard to encircle a big gray full screen empty frame. Thank you.

I'm running Firefox Dev edition and I cannot get it to load any pages except for Mozilla pages. I have tried all the fixes suggested there and it still refuses to connect. I'm at my wits end. Any hail mary optoins or do I have to reinstall and start again?
