Firefox Support Forum

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!

When I close firefox while it's in full screen, turn off my laptop, and then open it again the day after, it opens in the small screen for some reason. I tried going to the root directory in the about:profiles section of the more troubleshooting information section and renaming xulstore.json to xulstore.json.old, and each time it worked for a few days and then it just installed a new xulstore.json and went back to opening in the small screen. This is really annoying and I don't want to switch it manually every time.

When attempting to install an extension and clicking on "Add to Firefox" the button is replaced with a "Cylon" throbber and the popup dialog asking to confirm the install never highlights the "Add" button. The browser will stay in this state indefinitely until the tab for the extension install is closed.

Could this be a permissions problem involving the ".mozilla" directory tree in the home directory? I've been having this problem regardless of the FF version for some time (going back to at least v110.x). The recent issue involves that 115.9 ESR version installed in Debian Bookworm.

TIA...

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 ?"

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 view a lot of pdf documents via firefox, the light gray background makes my eyes and head hurt after prolonged usage. In the past I found a solution on this forum that advised to set pdfjs.viewerCssTheme to "2" in about:config. This set the background of pdf viewer to black/dark gray. This has worked for years until recently when the pdf viewer switched to light mode again (pic 1). I checked the about:config settings for pdfjs.viewerCssTheme but there appears to be no change. I tried restarting the browser, setting the theme to 0 and to 2 again, updating browser. Sadly the theme is still light gray. Is there a way to change it again? The desired outcome is in pic 2. I do NOT want to change the color of the pdf pages themselves.

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.

Just updated a friend's computer from Windows 7 to 10. Installed firefox over previous ESR and now there's no way to remove the search bar from the new tab page. On my W10 system, the search bar isn't there, not sure how or why, but on her's there's no option NOT to show it as there used to be.

I found some VERY old (2014) info on this but doesn't seem to be up to date.

PLEASE give us our options back and stop taking them away, sheesh, getting as bad as Microsoft.

Is there a workaround for this to remove the redundant search bar from the new tab page since you can search from the address bar?

Thanks!

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

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.

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 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"?

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 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 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.
