I'm using Firefox Developer Edition v136.0b5, and I'm looking for a way to remove “Turn on Vertical Tabs” from the contextual menu, because I'm so used to reopening a tab by clicking on what was then the last item in the list, that every time I end up with vertical tabs lol.

I have used Firefox for years, and especially since the ability to pin tabs was created. After this last update I experienced an issue on one website, which the tab is pinned, that was not present before. After putting things into my shopping cart, I click on the shopping cart and if the original tab is pinned then the shopping cart opens in a new tab. Before this latest update Firefox was smarter than that.

Is there a way to hide the top tab bar while I am using the Tree Style Tab option? I love the new option for using the Tree Style Tabs to my left, but it seems redundant to have the tabs on my left while also having them across the top. It clutters my window with too much text and I would love to see a cleaner window with just my bookmarks across the top and the tabs to my left. I can't seem to find a setting for that. Does one exist?

The new native tab group feature has an option to "Save and close group", implying that you can restore the group. But doing this, you will find that the group disappears.

Is this a known bug? Has anyone figured out how to restore a saved tab group?

I'd like to try enabling Tab Groups in Firefox 135.0 (64-bit). But I don't want to risk scrambling my gazillion or so tabs if Tab Groups is not stable.

I'd appreciate some feedback from Firefox users who have enabled Tab Groups.

I'm running Windows 10 version 22H2

(btw my browser is Firefox Nightly) Don't get me wrong, I love having vertical tabs. It's less busy than the horizontal tabs and I can look through my tabs more quickly. But, the way it's implemented sucks - It makes the layout of the webpage pop anytime I use it; there is no keyboard button attached to opening and closing the tab (I have to go through my horizontal bar to open my vertical bar); and recently my browser forgets the sidebar settings, meaning I have to re-check the "Hide tabs and sidebar" setting.

Bonus request Can the sidebar just go over the webpage (i.e. like the application menu) instead of squishing it? I'm ok with having some webpage features temporarily covered if it means I don't have to see the screen pop into a new rectangular shape every time I switch tabs.

Until now I have always used the mouse scroll key to open links in a new tab in firefox. Now it does not work anymore. I have to right click the link and choose to open the link in a new tab. Have been looking for a setting for it, but can't find it. Is this something new? I want Firefox to work as it has always done sincce I started using it many years ago. Please help!

I'm keep receiving mails to verify my account, when I open the link, it redirects me to my Mozilla account but everything seems to be in order and y don't want my account to be deleted. How am I supposed yo verify it? I have Two-step authentication, the Account recovery key, a Secondary email and I even singed in several devices.

Thanks in advance for the help.

This code in mozilla.cfg used to overwrite new tab, but as of latest firefox 136.0b1 no longer works. Any way to fix this? There error in Browser Console.

// mozilla.cfg needs to start with a comment line var {classes:Cc,interfaces:Ci,utils:Cu} = Components;

/* set new tab page */ try {

 Cu.import("resource:///modules/AboutNewTab.jsm");
 var newTabURL = "file:///D:/Documents/images/home.html";
 AboutNewTab.newTabURL = newTabURL;

} catch(e){Cu.reportError(e);} // report errors in the Browser Console

I recently updated to Firefox 135.0 on MacBook Pro, Catalina, OS 10.15.7 In the past, with multiple Firefox windows open & multiple tabs open in each, when restarting, "reopen pages on startup" selected, system loaded & ready to go, I'd find all windows, tabs & history available upon launching Firefox. Since update to 135.0, shut down & restart, launch Firefox and I find a single blank new window, no multiple windows, no tabs, no history. I've tried to find [Settings] to make everything come back - no joy, to no avail. Suggestions? Help? Thanks, JS

Hi, Recently had to reset my Pc and on installing firefox I find that I am unable to keep open the tabs I use daily, I keep getting the -close 7 tabs - I do not want to close my tabs on closure. Firefox always used to close - No asking to close tabs - and when I reopen all my tabs were still tghere. Whats Changed?

This feature has suddenly appeared and I absolutely detest it! I don't need it, don't like it, don't want it! I have searched everywhere on how to disable it. PLEASE tell me there is an option to do that.

Firefox has a feature where, if you select a tab and drag your cursor downwards while still pressing down on it, it will open that tab in a new window. Is there any way to disable this? I am frequently opening tabs in new windows when I'm just trying to view them and it drives me mad. I never use this feature intentionally- I am constantly using on accident due to quickly moving my cursor away from the tab bar to view the tab I just opened. Thank you.

Because I was doing research for an essay, I had a great number of tabs open in Firefox. Today, I had to run a full-system virus scan, and now all the tabs are gone. Is there any way to recover them?
