Firefox supportforum

When trying to install any extensions on either the Mozilla Addons website or directly via the Extension settings, it fails to do so.

I've attached a screenshot of the Mozilla Addons website when it fails to install the extension. On some other addons that I've attempted in the past, it just shows the throbber forever.

I have checked the Multiprocess Browser Console and it says that it fails to move the file because it's locked (NS_ERROR_FILE_IS_LOCKED). I have also attached a screenshot of that.

I've tried going into Full Screen mode three different ways:

• Clicking the green MacOS button in the upper left of the window
• In the Firefox menu in the upper right, to the right of the Zoom choice I click the full screen icon
• Pressing Command+Shift+F

But whatever way I do it, I still see the tab bar, address bar, and bookmarks toolbar rather than a true full screen. Not sure what I'm doing wrong.

I accidentally pressed a lot of keys on my keyboard and for some reason the default colors of Firefox have changed. I found out that by using Ctrl+Alt+D that I can switch the colors back to normal or to the colors that now appear automatically, but this only works for one tab. If I open a new tab, it shows the weird colors (see images below). I tried looking up specific shortcuts for Firefox considering the shortcut mentioned before (Ctrl+Alt+D) only works on Firefox. But I can't find any shortcut tied to that combination. I'm unsure what to do and how to fix this.

I would appreciate it if someone could tell me how to fix this.

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!

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.

In previous versions of FFx, toggling to Reader view used the same font I'd chosen in Settings / wherever. Now it's something else, in boldface with no distinctions made in original view (italics, not italics, etc). & there doesn't seem to be any way I can control fonts in Reader.

Any suggestions? In plain English, please, I am NOT a programmer or computer professional, just a regular human trying to use this new version that seems to have broken everything I liked about FFx.

I always want the address bar suggestions to start with my bookmarks. Is there a way to control the results? I remember there was something in about:config previously.

hi,

When can we have firefox with translation set OFF by default?

I mean, it's pretty unfair that intelligent people have to keep turning off the dumb translator... all the time... We need a setting, openly available, in the Edit/Settings menu, where it belongs, an option to switch it off. In fact, when it first asks if we want a page translated, we need an option: never ask this again...

All we can see is "go under the hood of firefox, config:option, go into the about:config section where 10 of 10 million people will ever get... and there find your way to disable this horrible translator". When can we expect an option in the pop-up: "never ask me this question again"?

The translator in this offensive form has been around since 2023... I seems high time we didn't have to bother with this anymore...

I already found many users asking the same, but they didn't get a reply.... at least I didn't see any.

I want to protect my password memory with a master password - fine. But in 99% of my time, I don't need to enter login data. Even worse, if FF starts on an "invisible" monitor, I cannot move the window.

Is there a way to have FF prompt only for the password if I attempt to log into a site ? ... it already does that when I cancel the start-up prompt.... so is there an "auto cancel at startup ?"

Hello everyone, I’m a fan of Firefox due to its efficient handling of webpage caching and memory management. However, I often find myself switching back to the Chromium-based Edge browser due to one specific feature in its DevTools. In Edge, when I resize the viewport, it stops at a certain limit. If I want to resize it further, I can zoom out and then continue resizing. I find this feature very useful. Is there a way to have similar functionality in Firefox? I’m currently using the Firefox Developer Edition.

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

Can someone please answer how to reset firefox size after you've been using a bigger screen and go back to the laptop the top bar is lost way up and I cant catch it to move it to resize the firefox window. Using Fn and F11 to go into maximize mode doesnt help me at all cuz I end up in full screen on the FHD screen but cant grab and drag the window to resize it again - and please NO comments about using FN and F11 again. This is an issue thats been since years - cant figure out why ppl who are tryin to help think others dont know the difference between maximization and the window being bigger than the laptop screen and being lost. So FIREFOX key-shortcut for window size reset URGENT PLEASEEEE - Im having this issue couple times a week. To fix it I gotta go again to the bigger screen reduce the size of the window and then disconnect - which is soooo horrible.

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

I sent an email to the support email given for this add-on but didn't get a response, so maybe others can help:

I'm using the 'Simple Tab Groups' add-on on my Mac computer and am happy with it but I have one question. When I click on a web link in an email (I use the native Apple Mail), it of course takes me to my default browser which is Firefox, and then within Firefox to the simple tab group that I had open in Firefox before clicking the link. Logically I guess that's reasonable behavior but typically that's not necessarily what I want; I'd rather it open the web page in my 'main' tab group.

Is there a configuration option to say: "When clicking on a web link in an email, open to this xxxxxx default tab group"?

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.

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.
