Hi,

I'm using FF on Fedora 39.

However Firefox does not remember any file associations. The MimeTypes.rdf file in the profile is missing and is also not created on restarting the browser.

In the options I've now set the configuration to "Ask whether to open or save files". Now I see a popup when clicking on a file however there is no checkbox with "remember this file associations" (or something similiar).

I'm using the OneTab add-on, Enabled. The icon no longer shows on the Toolbar, though it is on the Menu bar next to Firefox View.

I ran Remove and then Added it again, hoping the Toolbar Icon would reappear = no go, And I lost all URLs already saved, stupid me. To be clear, clicking the Icon on the Toolbar saves all open tabs.

Is there a fix via Preferences? Thanks. gw

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.

Hello

I want to use extension xpi's from a shared external folder over multiple Linux profiles. So i examined the profile folder and found extensions.json. Though i can't find any documentation to it's keys online.

There's "rootURI:" with a "jar:file://path/to/extension.xpi!/", so i tried just replacing the path with the shared one. Though i observed that just makes firefox replace the path with the current one. So i examined further and found the "location:" key with the default value "app-profile". So my guess is, there's other values for other usecases, right?

So, in summary, what i need is:

  • documentation to extensions.json keys or possible values to "location" key.
  • if that isn't intended/doesn't work, how i can achieve my goal otherwise.

And please don't suggest the sync feature, that doesn't work for my usecase.

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!

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...

Peter

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 ?"

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.

FF: 124.0.2: Grouping of Tabs

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.

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.
