Firefox Community Forum

After recent update, I can not browse any addons. The site https://addons.mozilla.org does not open, shows the connection timed out. I uninstalled and reinstalled firefox deleteting all firefox related files. The problem still persists. Other than this all the using browsing I do are all working fine. Just this extensions I cannot browse. When I click the extension icon by default it shows some extensions, I can Install them. The problem is I can not browse them. Even the recomendation tab is also empty.

PS: I am using firefox on manjaro linux.

Hello, after a power cut I lost all my bookmarks. When I try "Manage Bookmarks -> Import and Backup -> Restore -> Choose File..." nothing happens.

In the folder ".mozilla/firefox/6924v31j.default-1728390329118/bookmarkbackups" there are several backup files, but the newest has the date Jun 25, though the name suggests it's from Jul 2: -rw-r--r-- 23850 Jun 25 13:07 'bookmarks-2025-07-02_184_mg1znof1NbBiyJ14ZcO9SluvTvLZI-rxPSm20YZUJww=.jsonlz4'

In the directory ".mozilla/firefox/6924v31j.default-1728390329118" there is also places.sqlite from Jul 4 11:59 (that was the moment when the power was cut).

How can I restore my bookmarks?

I have Firefox on 4 separate devices (Windows 10, Windows 11, Linux Ubuntu derivative x 2).

For the last 2 weeks, every time I open Firefox, the recommended stories are active. I go into settings, turn off the setting and it behaves correctly for that session. However, when I open Firefox on a different device, or the next time, recommended stories are showing once again. I like and want a clean, minimalist interface, and expect Firefox to honour my settings.

Thank you.

latest versions of firefox (now at 140.0.1) keeps opening onto my 2nd monitor which is off - how to stop it doing it. Tried making new profile which works for awhile, but sooner or later they all bump it to the 2nd monitor and it never comes back - tried moving to primary and closing it there, but next time back on #2. Open 2nd window while first is on primary, and that goes to 2nd monitor...

Hello,

I changed the default font on firefox the other day, and now most things from the browser are rendering in that font. I tried to change the font back to what it was before because I decided that I don't like how it looks, but now that I have changed all of the fonts back, they will not change to the new selection. I have restarted firefox multiple times and even my computer in the meantime. I don't know what the deal is.

For some reason text rendered in canvases (used by Minecraft hostings to display console) is distorted. I'm not getting this behavior in other browsers (including Zen – Firefox fork). The issue persists in both stable and nightly versions, with and without hardware acceleration, in safe mode too. Any clues?

The setting works...in the way that if i quit Firefox, it'll not continue from the tabs and windows, but if i reboot my pc and open Firefox, I find myself the same place i stopped...even though i have that setting disabled. I found someone else with same issue on reddit and i did the same restarting the browser and refreshing and all....all to no effect.

I have autoconfig.js set up to run my own js file, see below. The intention is to change the keyboard shortcuts (shame that it's so difficult😃). It worked until a few weeks ago. Now it only partly works. C+J is fine. The other two succeed in deleting the existing command, and the shortcut key does nothing. Any ideas please?

// C+J = open downloads var element = document.getElementById('key_openDownloads'); if (element) {

 element.setAttribute('key', 'j');
 element.setAttribute('modifiers', 'accel');

}

// C+D = Duplicate tab var element = document.getElementById('addBookmarkAsKb'); if (element) {

 element.removeAttribute('command');
 element.setAttribute('oncommand', "duplicateTabIn(gBrowser.selectedTab, 'tab')");

}

// CS+N = move tab to new window var element = document.getElementById('key_undoCloseWindow'); if (element) {

 element.removeAttribute('command');
 element.setAttribute('oncommand', 'gBrowser.replaceTabsWithWindow(gBrowser.selectedTab)');

}

Bonjour, Je veux modifier ces sites webs recommandés. Des "top sites" ça s'appelle je crois. J'ai regardé sur le net mais j'ai pas vu comment les modifier. J'ai par exemple, pas besoin de Le Monde ou de Reddit. Cordialement, Un utilisateur
