Firefox supportforum

I currently have a 'bad/rouge' session of Windows 7 Firefox (don't really know how that happened) open (7 'Windows', each with one empty Tab plus 1 'Window', with only 1 populated tab (Yahoo Mail)! I need to close Firefox in order to restart my laptop (strange things have been happening, including not being able to access the internet)!! On restarting, I want to be able to open Firefox with the previous session I had with my 8 'Windows', each with dozens and dozens of Tabs! Please help, I sorely need those many 'Windows' and Tabs!!!

At one time, I was able to swipe left on my trackpad and go back to the previous page on firefox. I can't seem to find where to set that preference. I'm running MacOS.

in the firefox browser is there any way to see the casting the browser screen to chromecast on tv. similar to 'cast to media device' in edge browser or chrome browser.

Sometimes all add-ons / extensions break randomly and are disabled (the icon of the extensions is also broken under "Manage Your Extensions").

The extensions are visible under "about:addons", but the slider is turned off and the icon in front of each extension is broken / empty.

It seems that deleting these 2 files- compatibility.ini and extensions.json inside the firefox profile folder, usually fixes the issue. Only these 2 files though, don't delete anything else.

No need to mess around with the ff profiles or anything else, just deleting those 2 files and restarting the firefox usually fixes the issue with the "unregistered" addons.

This thread is for the search function, as I found some VERY old and outdated suggestions for the aforementioned issue using the search function.

I wonder what causes the extensions to "unregister" randomly.

To open a link of a website in the background tab is CTRL+click, why is it that to open a bookmark of the bookmark toolbar in the background tab is CTRL+shift+click. It is confusing! A bookmark is a link! For comparison, both of them are CTRL + click in chromium. BTW, there is no explanation in advanced configuration preferences.

remove ad blockers even though I already have removed them.

printer is not recognized as being online although my other devices don't have the problem. i use Firefox on all devices

Hail all:

OS: W11Ent_x64 V: 22h2 (b: 22621.3447) FF: 124.0.2 x_64 I tried several "Group Tabs" add-ons, like: Simple Tab Groups. Tab Group. And I few I can't even recall the name from. Yet, none works. Not ONE.

Now, I use Edge as well, on my corporate system that I got from work. Personal PC I use FF on.

But, the Edge Tab Grouping, which allows tabs to be "put to Eco-Sleep", while hidden the open tabs by clicking the Group-Tab Icon, is a feature I sorely miss in Firefox.

Odd, as, so many requested this feature, how come it has not been implemented over the many years of people asking?

Either way: Does anyone know a good, WORKING add-on that does the "Edge Thing" with FF tabs, please? Since, I often got like 200 tabs open, which is a real misery without Tab Grouping and "Hiding".

Thank you aforehand: Ke'Ylan.

I frequently attempt to open news articles or other pages requiring form fill-in but instead get a page that advises me to disable an adblocker. I have no idea what Firefox (yes, up-to-date) uses or how I could set it to allow pop-ups for a particular site. Help!

I know that it is possible, cause, in the past, I had extension doing exactly that. When I click on an active tab, Firefox just minimized it and went back to the last one I was looking at. But it was for the old version of Firefox. It wasn't compatibile with the new ver of the brawser. Can anyone can help me find some extension doing that please?

Ever since the latest update, the picture-in-picture function stopped working properly. If I activate it, the video will automatically go to full screen, and I need to press the full screen button multiple times to move it down to a small box. I am using Firefox on a Mac laptop.

Lest update to 15.9 all my extensions are now disabled. Missing Lastpass and Surfshark from my menu bar. Doesn't seem to be any way to Enable them from Extensions screen.

I reloaded Lastpass from their site and this is now working on my Menu bar.

But what happened to cause this

Hi, my proxy configuration settings got selected to No proxy and I'm unable to update it to auto proxy/manual proxy configuration settings as you can see in the below image, the pop got disabled and unable to select other options.

Actual result: unable to edit the proxy configuration settings got selected to no proxy and editing is disabled

Expected result: should allow user to select the below configuration options i. Auto detect proxy settings for this network ii.use system proxy settings iii.Manual proxy configuration

When in fullscreen, if I move the mouse to the top-left corner and right click, a browser context menu appears. The page I'm on is using mouse right clicks, so this browser function is breaking the controls of the page if I ever accidentally click the top left corner (which I do often).

Is there any way to disable this menu appearing? I would never use this menu to minimise/close the program so I just want it gone. It's breaking fullscreen controls in it's current form

I use a public computer often, and I would like to use certain customizations while remaining anonymous. Rather than going through and clicking a bunch of checkboxes, I decided to have a hot key combination to enter in order to obtain my desired options. For example, I want to allow new windows to open normally, I want to choose where files are saved, and I want to turn off Firefox's recommendations. The underlined hotkeys are, respectively, ALT+W, ALT+A, and ALT+R ALT+F. So rather than a bunch of scrolling and clicking, I could just type ALT+WARF, and get the options I want quickly.

However, pressing the hotkeys while in the settings does not seem to do anything. In particular, pressing ALT+WARF only succeeds in pressing the ALT+F, which opens the File menu. Pressing these keys without an ALT key sends them automatically to the search bar -- which is also not what I want. Pressing ALT+SHIFT focuses in on the checkbox -- but does not press it. For example, ALT+SHIFT+W focuses on the checkbox, but I still have to click SPACE after it to press it.

Is this a bug? If not, how can I make the underlined keys press the respective checkboxes?
