When I have set the size of the window and then move the window to the left or right then the application automatically expands the window. I do not want it to do that as I want to be able to have the firefox window where I choose and the size I have chosen, but the program automatically expands the widow to fill the screen.

Hello, please, how do I add a "Share Tab" Button to the Firefox Menu? I'm using Version 149 on my iMac (late 2013, running V. 10.15.8). I'd so appreciate your help with this? Thanks in advance, Eliahu

Hello,

I have two windows in Firefox that I would like to tile so that I can compare the contents of each. Is this possible ? Regards

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?

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);

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.

how do I click ok to do this? Double-click the browser.sessionstore.max_tabs_undo preference to display a dialog where you can enter the desired value, which in your case might be 0 and then click OK. I have an HP desktop running windows 11 and have been unable to prevent history from keeping recently closed tabs.

not a real question and not waiting for answer.

the "Open all in tabs" menu that appears at the bottom waiting for you to click on it by mistake. we need a way to remove that option while also disabling the middle button over the folder to open all bookmarks over the tabs. It also should be a default because been using firefox since version 1 (previously Netscape Navigator back in 1998) and I rarely had the need for something like that.

asked chatgpt and it suggested some fixes but apparently userChrome.css is actively being ignored. from the look of things, seems like I will have to stick to an specific version like I had to do with Thunderbird after version 102 where ugly UI changes were implemented.

have fun.

I went to settings, general and tabs. While I was trying different tab settings I accidentally changed the function of the F11 & F12 tabs. How do I return them to their default setting?

After a recent change the browser scroll always goes to the bottom of the page. Before it was always at the top of the page. I found no way in Firefox to reset this function.

Hello, Firefox. So I have this feature whenever I type. When I type my first letter, it is capital, and whenever I add an comma to my sentence and hit the space key, it adds an period. I don't remember enabling that feature, and I want to disable that feature. Is there any way if I can disable that feature? Thanks in advance!

I am using Debian Trixie with firefox 148 and I reported that the refresh option was missing from Firefox, https://support.mozilla.org/en-US/questions/1569549. I then noticed another workstation with the same version of FF that did not have the "refresh firefox" option.

It appears firefox has been changed. Some of the items have been changed including the profiles option to add color on creation.

How can the parameters of FF be changed ? See enclosed menu under help, "more trouble shooting information", you will see "refresh firefox" is missing from the top right.

Mozilla currently allows a user to select an AI Chatbot to use in the updated sidebar. The choices are limited to Anthropic Claude, ChatGPT, Google Gemini, Le Chat Mistral and Microsoft Copilot. When will Mozilla add Grok to this list of choices?

I have reset Firefox as default browser on my Windows 11 PC a hundred times in the past few months. Today, I could not reset it at all -- I click the default button in Windows 11 and as soon as I close that settings window, it disconnects. I've run out of things to try to fix this. I think it MIGHT be related to Norton 360, because I first notice this problem when I opened Norton.
