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.

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?

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.

Hey friends, n00b questions - how do I allow pop ups on a website again?

I accidentally clicked too fast and clicked to not allow pop ups again on a site I need a window to pop up.

I went to settings to make an exception for the website, but it still does not work.

Any help please?

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.

Mozilla gave assurances that AI features would be opt-in. The most recent update automatically turned AI features ON and I had to open settings to block them. This is opt-out, not opt-in. I find this betrayal of my trust as a longtime user disturbing.

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.
