I-Firefox Community Forum

I host a website, and don't want browsers (particularly Firefox) offering modified versions to others. Is there a header or something I can set webserver-side to disallow Firefox from offering the option?

This doesn't work:

add_header Cache-Control "no-store, no-transform, public" always;

I'm trying to stop Firefox from restoring tabs after I restart my OS. So far, I've done the following:

• Disabled `Startup > Open Previous Windows and Tabs`
• Disabled all extensions
• Confirmed I do not have a `user.js` file
• Set `browser.sessionstore.resume_from_crash` to `false`
• Set `browser.sessionstore.restore_on_demand` to `false`
• Set `browser.sessionstore.resuming_after_os_restart` to `false` (It was already set this way.)
• Set `browser.sessionstore.max_resumed_crashes` to `0`
• Set `privacy.clearOnShutdown.openWindows` to `true`
• Set `browser.sessionstore.max_tabs_undo` to `0`
• Set `browser.sessionstore.max_windows_undo` to `0`

(I've since reverted the last two and the extension changes after they didn't work.)

So far, Firefox will not restore tabs on application restart (manually closing and relaunching) or on crashing (after sending SIGTERM/SIGKILL), but it still restores tabs after restarting the OS (if I allow the OS to kill it during shutdown). I've seen a couple suggestions to disable history completely, but I do occasionally refer to my browsing history, so I'd prefer a less-drastic approach. Ideally, I just want Firefox to treat the first launch after a shutdown as a normal launch and not apply any special behavior. Any help would be much appreciated!

I am using Mozilla as my default web browswer in Unix environment. It is great... except for a particular behavior of the browser window. When I middle click (MB2) the frame of the window, it doesn't go to the background, like all my other windows. Intead it opens a new tab (when I click at the top of the window). This is very annoying becaue I use MB2 /go to background all th etime. Any idea how to change that behavior and make it consistent with my general unix preference? Here is how it looks: see attachment.

Thanks in advance.

Is there a button I push or a feature I enable to make sure that I'm opted-out of any future updates that include AI 'features'? Or should I switch to Vivaldi now and save time?

Hi, new Firefox Win 11 user, new laptop, how do I enable main touchscreen gestures, swipe, pinch etc. All other apps, browsers work, so HW / drivers work. Can't find how on user forums, or in settings.

It appears even though I'm not using Firefox's auto-spelling feature. It now appears in the right-click menu. I've never seen this before, so is this a "new feature"? I want to delete it because it is not necessary in my environment.

I search but did not find any list of environment variables supported by Firefox. Is there such an official list, perhaps groupped by Firefox version, published somewhere?

I need to know how I can stop my overflow bar from appearing whenever I click off and then back onto FireFox.

Steps to recreate starting in FireFox: 1. Click on an application other than FireFox 2. Click back on FireFox and then the overflow menu appears 3. Click anywhere on your FireFox window and it vanishes until step 1 & 2 are repeated

Hello,

I use an online text-based website frequently at work, Firefox is my chosen browser for many reasons. One problem I am facing is that when I go to make text bold using the shortcut Ctrl+B, the bookmark bar appears on the side of my screen.

How can I disable this, as it does get in my way frequently, having to close the bar before I continue.

I’m can not get fire fox to be my main not default on my Apple macOS High Sierra i5 ‘I spoke to ur colleague earlier and said that because it’s old it will still work in firefox ——basically it’s an older version and now where it used to say google or chrome it doesn’t say fire fix it says directory utility please help

I admit, I don't read about updates so I don't know when Firefox did all these "enhancements"...but I'd love to know how to turn my mouse wheel BACK into a "scroll through the page" only function. I hate it auto opening links, I hate it scrolling through tabs. I suspect it of doing other "helpful" functions...and I can't even find the right words to do a search for this. The only applicable setting I found is "autoscroll"...which is turned off in my preferences...and which the browser STILL does.

All I want is for my wheel to scroll through the page...under my control. No auto-stuff. There's no setting for this in my mouse controls, as far as I've been able to determine, and it didn't used to do this. It must be in a Firefox update. Is this even possible any longer? Or am I, after decades with Firefox, going to have to change browsers? At this point, I've had far too many important operations disrupted and even fouled by this "helpful" change.

Pleeeease help?

I have the source set to open in the editor. When I start Firefox with a blank editor open and open the source, the source is not displayed in the editor. What could be the cause?
