When I select a line of text, normally it would get deleted/overwritten when typing a new line of text, but when I select text in Firefox and begin typing again, it simply deletes the first word in the selection and keeps the rest. Is there a setting to have ALL text selected deleted/overwritten when new text is entered? Selecting one word overwrites the whole word but when an entire line to be deleted is selected, only the first word is deleted and typing begins where that word ends.

I only use Firefox to play two browser games that both use the 1-5 keys as an alternative to clicking the mouse. Accidentally clicking Ctrl and switching tabs out of nowhere is becoming a really annoying problem, but I don't see any way to just turn off shortcuts and hotkeys like other the other browsers I use. Is there any way to do this? Even a specific extension that makes the Crtl button do nothing would help, the one I was recommended won't download due to a "corruption".

Over the past few updates, I’ve noticed an issue with Firefox where it no longer restores my previous session when reopening the browser.

I normally keep four tabs pinned and about five additional tabs open for browsing and work. In the past, I could simply click the X to close Firefox, and when I reopened it, all my tabs that are pinned and unpinned would automatically come back. Recently, this stopped happening. Now, if I close Firefox, it opens with a fresh window instead of restoring my previous tabs.

I’ve already checked the setting under General/Startup, and Open previous windows and tabs is enabled. Because of this issue, I avoid closing Firefox entirely, since rebuilding all my tabs each time has become a hassle.

Is there a way to fix this? Any suggestions would be appreciated.

Thanks :)

It was nice when FF was simple to use....unimcumbered with all the options...like the latest...profiles.

Why? It's getting to be as complicated as E and C..you don't need all those options - that's why I use FF.

Get rid, or allow the user, to pick and choose, and dump the unwanted stuff from cluttering the tool bar and other options. Just a suggestion that can be made to FF any longer. Use to be they'd welcome feedback.

This might be quite "old man yells at cloud" of me, but oh my god I am so fed up of everything putting AI in as a "feature" for no reason.

1) No one asked for this. 2) It is bad at doing whatever it is designed to do. (It's not helpful, it's not even neutrally unhelpful, it's ANTI-HELPFUL.) 3) It is always on by default, or worse, impossible to turn off.

At the very least AI features need to be off by default, because it's rubbish.

Firefox is meant to be a bastion of sanity and safety in a world of exploitative techbros trying to steal our data and trick us into making money for them. So-called "AI" goes against this. Please, Firefox, be better.

As of 20th Nov 2025, here's how to turn off AI features. Go into about:config and set all of these to false (yes, you’ll have to copy and paste them one by one):

• browser.ml.enable
• browser.ml.chat.enabled
• browser.ml.chat.menu
• browser.ml.chat.page
• browser.ml.chat.page.footerBadge
• browser.ml.chat.page.menuBadge
• browser.ml.linkPreview.enabled
• browser.ml.pageAssist.enabled
• browser.tabs.groups.smart.enabled
• browser.tabs.groups.smart.userEnabled
• extensions.ml.enabled
• browser.search.visualSearch.featureGate

in addition to nuking AI, it’ll also speed up your browsing

I want to delete Preview Links. I tried going to Settings>General>Browsing, however, there is no "Browsing" section. I have a Linux Mint. I do NOT want Preview Links. Thank you.

i have no use for the 'profile' tab on the tool bar, how do i perminately remove it? i can not drag it to overflow, it drags the entire toolbar. very frustrationg. also i have no need or use for 'open in split view' in the right click menu. all both of these things do is clutter up the tool bars. please make it easier to remove these things.

zen_browser has this feature which I use multiple times per day every day: keyboard shortcut ´shift+cmd+c`to copy current URL to clipboard.

This is such a useful feature. It helps me save time and speed up my workflows a lot, so much that it's absence in Firefox is preventing me from going back to Firefox.

The feature was implemented in v1.6b back in early 2025 in zen_browser.

I am uncomfortable with the push for unnecessary ai content and features on firefox and if they are added without easy ways to remove or disable I will be switching to a different browser

On a brand new profile for Firefox without configuration of any kind I get an AI chatbot in the sidebar and AI tabs suggestions.

Why?

Is Mozilla looking to destroy decades of good will?

Anything like this should be something you have to opt-in to see, not try and opt-out of.

If privacy is a true concern then any of that stuff should be an extension, and not something on by default.

I really don't understand why Mozilla is doing this.

With the latest Firefox 149, the firefox-l10n.js in omni.ja seems to be gone? its normally located in \defaults\preferences\ the file is now completely missing in the omni.ja is it now named differently or is it migrated into another file? normally i edit the file and add for our deployment: pref("network.proxy.type", 0);

The last update (which was VERY rocky... I had to reinstall and functionality has NOT been great since) eliminated the Bookmarks icon from the top ribbon. I've looked through settings, but find no way to restore it. Can it be restored? I now have to click the menu, Settings, and THEN Bookmarks.

I often use the key combination Ctrl+Alt+X in Google Docs when on different devices but it doesn't function properly when instead it brings up the AI sidebar gadget. Removing the sidebar button doesn't really help and it's annoying. So how exactly do I turn off the key combination for the sidebar?

Hi, I unchecked something in my settings and I don't know what I did to cause when I right click to copy something there is no copy and a lot of the rest of the options are no longer there as well. Can you tell me what to do to repair this? It doesn't give me the option to take a screen shot either or I would show you what's left in that popup box. It only give me "Ask an AI chatbot" and the "translate".

Have a nice day, Tom

I am seriously concerned about the upcoming use of AI in Mozilla Firefox. The only reason I use Firefox is because it is one of the few remaining widely compatible browsers that allow me to switch off any AI features. Generative AI is needlessly wasteful and absolutely pointless. Is there any way to prevent this from being forcibly added to Firefox?

I am happy Firefox released a way to change system shortcuts in the most recent version. But a shortcut I've wanted to change for awhile was not present.

Cmd+K (Jump to OmniBar)

Is there anyway to change this shortcut? If so, how?
