Dear Mozilla Firefox Team,

I hope this message finds you well.

I would like to start by expressing my deep appreciation for the Firefox browser. I truly admire the values Mozilla stands for, especially regarding user privacy and open-source development. Firefox is fast, secure, and beautifully designed — and I would love to use it as my primary browser.

However, there is one major challenge that prevents me from doing so: extension compatibility. Many of the tools and extensions I rely on for my daily work are either not available on Firefox or do not function as they do on Google Chrome.

I understand that Firefox has its own extension ecosystem and architecture, but I sincerely hope that your team could explore a way to bring full compatibility or at least broader support for Chrome extensions. This feature alone would make Firefox the perfect browser for users like me who value both productivity and privacy.

Thank you for all the hard work and innovation you bring to the web. I look forward to seeing how Firefox continues to evolve.

Best regards,

Hello! I am an avid user of firefox (especially with adblockers) on a windows 11 PC. Unfortunately, I have recently been experiencing an issue where when I attempt to open firefox, a window will open for a split second before instantly closing again. My PC is up to date, I have tried refreshing firefox and doing a clean install, but cannot seem to overcome the issue, or even open it in safe mode. Does anyone have any advice? Many thanks in advance!

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)

My firefox browser crashed last week. An IT expert uninstalled it and re-installed it and it is working ok. But when I try to buy goods online my stored card is being rejected but I don't know why. Can you help please?

I have some websites that require pop-ups. I cannot get them to work in Firefox on my Android phone. Google searches reference a setting under "privacy and security" where I should be able to allow pop-ups in general or for certain URLs only, but I don't have that setting option.

I have Firefox version 139.4 if that helps.

Thanks in advance, Paul

A little square used to pop up when I clicked on the searchbar on my iPhone, but it seems to have stopped doing this with the latest release. Can anyone please help me find it, or if it has gone, then please confirm to me?

I can still open QR codes by opening the Camera App first, but the Firefox QR code reader was always easier to use, and I just like it more!

I don’t seem to be able to add a Home Button within the Browser since it updated to the latest version. This is very frustrating as it gets used all the time. Please explain how I can add a home button.

Kind regards

Wayne

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.
