when i open firefox (including opening a new tab) my CPU peaks at 100% on all cores for a few seconds. this is without any pages loading and without many heavy extensions (all i have is malwarebytes and dashlane)

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.

My mail checker extension isn't working right in Firefox. Extension Link I was able to find an error using Developer Options but I don't know if the error is even related to the extension or if it is even useful. If anyone would help me, I would be very grateful.

HI Mozilla, I have recently purchased a new laptop and am setting up my desktop icons. I have the latest version of Firefox on both the old one and this one. also Windows 11

On the old computer (which I set up 18 months ago and still works) the desktop icons show the website logo. The correct logo appears for any newly opened websites for which I set a desktop icon.

On this computer all website desktop icons show the Firefox logo and not the website logo. This happens whether I drag the address or the lock symbol. I can change the icon using the inbuilt menu, but this is tedious and I would prefer them be the correct ones.

The correct logo appears if I right click on an app in the start list and drag it to the desktop.

Consequently I think the above is a Firefox problem.

I have been using Firefox for some years very successfully.

I do not like the function of opening last page I was on when restarting firefox. I use a program to help eliminate my browsing history. foxfire brings up last page I visited and ruins the work. I have un-checked open last page but it does not help. The program cannot get to something in firefox to erase my history. I like firefox but will discontinue use If I cannot resolve this issue thank you, I am very frustrated.

hello. i downloaded firefox from official void linux repo, and have issue with font rendering or smth. in settings option "Allow pages to choose their own fonts, instead of your selections above" is enabled. don't have same issue in any other gtk apps on my system.

I get notifications from Firefox browser saying that I have messages, but if I click on the notification it just opens the browser and doesn't take me to the message that I clicked on. I can't seem to figure out where said messages are hiding. It's a little frustrating. Can you please tell me where these messages are at? It will be greatly appreciated. I took a screenshot of the Firefox version I'm running. I hope that helps.

I want to set firefox to use noai.duckduckgo as my default search engine so I can continue to type queries in the address bar. How can i change the settings to include noai.ddg as a default option?

There are four (!) instances of Firefox now in Default Apps (Windows 11). From what I can glean from searching online, the fixes either involve messing with the Registry or uninstalling/reinstalling Firefox, but even these measures do NOT prevent the multiple instances from recurring with further updates. The Control Panel only shows one instance of Firefox.

What is the best approach to this problem? A "fix-it" tool would be most welcome.

Chrome user returning to Firefox here; I'm experiencing an issue where most pages would take at least 4 to 6 seconds to load, especially for heavy media sites like YouTube which could take 6 seconds for it to be barely usable, and 10 or 13 seconds for it to finish loading. My internet speed is 1gb at most and 800 Mbps at the least.

It loads sites like Reddit pretty fast, like 3-5 seconds interestingly. It's largely YouTube and other sites where the pages load infuriatingly slowly, and Chrome Mask did not helped with this.

Here are the things I did: Refreshed Firefox, started in Troubleshoot mode, installed Chrome Mask for YouTube (Did not work), disabled DNS, closed all foreground apps except Firefox, used a different profile and enabled/disabled hardware acceleration.

Specs: CPU: i5-3570k GPU: GTX 1070 Ti RAM: 16gb DDR3 OS: Windows 10 Hard Drive type: SSD

Final notes, it says I use Microsoft Defender Antivirus but I am actually using Malwarebytes. I also use uBlock Origin which is the entire reason why I permanently switched from Chrome to Firefox.

Lately I installed a new PC, and tried to download FireFox and sync my data. But my data seems like a few years ago, not as new as another PC I have now. I'm sure I have logged in with same account on them, how's this happend?

A few days ago, my Firefox installation stopped auto-completing my URLs. I didn't think much of it. But I tried looking up my history and bookmarks today, and they're both gone. History won't update, and I can't add new bookmarks. In-page autocomplete still works.

My Firefox version is 140.0.2 for MacOS on an M1 Mac Mini. I'd recently update my computer's operating system before I noticed the issue, and I had to do a hard power-down a day or two afterward. I do not know if the issue began before or after the hard shutdown.

How can I use ECOSIA as my search engine? ECOSIA is a search engine that "plants trees." I'd like to support the environmental nature of it.

Thank you, Michael

Firefox has shortcuts at the top of any new tab opened. These are usually your most visited pages. For most shortcuts, if you click the three dots you get a menu of: Pin Edit Open in a New Window Open in a New Private Window Dismiss Delete From History

This is the menu you get for almost all shortcuts EXCEPT for Amazon. For the Amazon shortcut you get: Pin Dismiss

That's it. No opportunity to edit it. And if you click on the shortcut, it doesn't take you to Amazon.com, instead it opens "Amazon.com Search" in the address bar. I don't want Search, I want to go to the Amazon home page but the shortcut doesn't take me to the Amazon homepage like it used to. Why is this broken now?
