ALT-SHIFT-LEFT has been 'select word backwards' for years, at least on macs. And so it was on FF too. Now they suddenly decided to re-map it to 'select left tab'. There was already a key for that - CMD-ALT-LEFT. Which also works for the right, whereas ALT-SHIFT-RIGHT does nothin

As I understand, `autoconfig.js` (with `firefox.cfg`) can be used to have JavaScript run during startup to control Firefox's UI elements.

I have set up `autoconfig.js` in my `/usr/lib/firefox-developer-edition/defaults/pref` folder (I'm on EndeavourOS Linux). As instructed here, I've already put the two required files, `autoconfig.js` and `firefox.cfg` in their correct folders (`/usr/lib/firefox-developer-edition/defaults/pref` and `/usr/lib/firefox-developer-edition` in my machine).

The file `firefox.cfg` contains the following code:

 //
 (() => {
   var tabbar = document.getElementById("TabsToolbar");
 })();

However, every time I run Firefox, this message will appear:

 "Failed to read the configuration file. Please contact your system administrator."

If I empty out the `firefox.cfg` file, Firefox will run normally without showing the error message. It will also run normally if I just have something like this in the file:

 //
 (() => {
   var testVar = "";
 })();

I don't understand why the JavaScript code can't access the Firefox UI elements through `document` or `window.document`. If `autoconfig.js` isn't build for that, what should I use to change my browser's UI elements through JavaScript?

Thank you.

Good day, has anybody an idea if and what addon could manage for me redefinition of mouse behaviour. Particularly in my case I want to use middle (wheel) button single click over any text input to perform clipboard paste (but everywhere else the button behaves normally). I had this feature integrated into mouse gestures add on which is no more compatible.

Hello, I just got a new laptop with windows 11. I just did the latest update to Firefox. Everything is a little large but an internet search addresses these: BUT.... The 'bookmark this page', the star in the URL line, menu is small and the fonts are micro. Zooming or changing fonts in the hamburger menu doesn't correct this. Attached. Thank you.

Hello

There seems to be a new function that opens a quick search window when I press the apostrophe key. This function is active on many websites, and I am using Firefox 125.0.3 on a Macbook Air.

This new function makes it very difficult for me to practice touch typing in Firefox, and I would like to turn this function of.

Best regards Max Andersson

I use an translator extension for firefox for russian so I do not need this integrated tool and it's annoying to see it everytime I open a russian page. Please help me, I don't know what the source is of this translator but I can tell it's not from an extensions as I deleted every extension and tried, not worked.

I like Ctrl+Shift+B to open the Library (Manage Bookmarks/Show All Bookmarks). For maybe two years I was using this, but it stopped working in 117:

Dorando keyconfig isn't current. Shortkeys won't even install and probably won't do what I want anyway. AutoHotkey will do it, but I'd rather not use it for this.

Does anyone know how I can get a config.js to open the Library when I hit Ctrl+Shift+B?

When I download an image in Firefox and open it from the downloads folder it will always open in Pixelmator not Pixelmator Pro.

If I double click on an image file elsewhere they correctly open in Pro, but in Finder, the icons are for Pixelmator not Pixelmator Pro. This can be hidden if I turn on finder icon previews, but selecting Get Info always has the Pixelmator icon not the Pixelmator Pro one.

Im not sure if this is a macOS problem, a firefox issue or a Pixelmator bug but it seems to be related to the way the files are registered.

Things I have tried:

Changing file associations in firefox. Rebooting Changing the open-with properties in finder: Open all with Pixelmator Pro Reset the Local & User domains with lsregister lsregister -kill -r -domain local -domain user -domain system -v

I have Firefox set to "view PDF files in Firefox", but this is not happening with sites like Capital One and Consumer's Energy. these sites are just saving directly to my downloads folder even though I 1) Want to view the file first and 2) if it is going to save a flle, it is set up to ask where the file should be saved.

Neither of these things are happening even though I have them set up correctly in Settings.

When I try to detach a tab, so that it's a new window, by dragging the tab downward so it isn't on the tab bar. After I let go a new window is created for that tab that I dragged, however it also maximizes the window, which disorients my work flow. Is there any way I can detach a tab into a new window and not have it maximized automatically?

Saved themes in Firefox color not visible in add-ons manager. Does not fix itself in safe mode. One of the saved themes is a default preset I liked, the other is a preset I made myself, using all options except advanced colors.

Firefox has started making a piercing high-pitched screech when the "save image" and "file update" panels appear. This is a confirmation or alert sound I suppose. It occurs when saving an image from a right-click menu and when downloading a file. Formerly Firefox used the system default sound for this, and that sound is still working in other programs for similar operations.

How can I fix this? Or alternatively how can I disable the sound during such operations in Firefox (or alternatively system-wide)?

When scrolling down I choose to read an article in a new window. When I open the new window, on the right side, a pop up window appears titled “Join the Conversation” or “More from Daily Express” blocking some of the article’s words. How can I stop this pop up window from appearing? Thanks.

Is it possible to spell check the entire web page using both Hunspell built-in dictionaries and user-defined dictionaries *.dic, already prepared text in Firefox. As it is done in text editors like Libre Office (also uses Hunspell) but for web site, checking the text from top to bottom with errors in a separate window, so spell check is not only in the text input/search field.

Hello

Since an update from a few days ago (May 2024), my address bar/search bar is now basically outside of my PC screen, see here: https://vimeo.com/948314161

It's not a local problem, it's also happening on other PCs/Laptops I have.

How can I fix this? PS should the answer be that I need an add-on or anything like that, then it's bye bye Firefox, hello Chrome

Thank you

I went to open a new tab today and suddenly the font or scaling on my menu bar got way bigger. It's extremely annoying, and I can't find any way to re-scale it, as all the zoom or font settings seem to affect only web pages, or the scaling of the entire browser window, including content. All the content in a browser window is fine, its ONLY the menu bar. I wonder if I hit a hotkey by accident when trying to open my tab (I used CTRL+T, but it's possible I accidentally hit another key instead or in addition to) but it's driving me up the wall.

With previous versions of Firefox (before 108.0.1) I was able to make changes with about:config to allow a default domain id .com to be added to my Internet query. Example I enter cnn and would get cnn.com and assess the website. WIth 108.0.1 I enter cnn and Firefox cannot find the site. The about:config changes I made are:

 set browser.urlbar.autofill to false, set keyword.enabled to false and set browser.fixup.alternate.enabled to true. 

The changes are mentioned in the incident https://support.mozilla.org/en-US/questions/1142103.

With 108.0.1 how can this be implemented like in the past versions? Thanks
