I am an editor, which means I do a lot of research. I do not want my shortcuts to reflect all the crap I have to review for work. The latest update shrunk the size of the shortcut squares and added many. That simply does not work for me, and I want to return to what I had before the update. Is there any way to do that? What I have now is a royal pain in the butt.

I use the most up to date Firefox program. I needed to reinstall windows from scratch so backed up my files using the Firefox Backup option. When i try to restore the files, it restores only 2 bookmarks, 1 called Learn More, and another, a folder called How to Restore, and in it a book mark called Download. The bookmark just takes you to the Firefox home page. I dont know what to do.. there are bookmarks I need, so hope someone can help. Attached is an image of the file Firefox Created.

I have tried accessing various Websites, including Google.com; DuckDuckGo.Com; whatismyipaddress.com, and this Mozilla support page. For each, I recieved the message: "Unable to find the proxy server". Turning the Firefox VPN off immediately enablabed the Websites to be loaded.

As you will appreciate, putting Websites on the exclude list should be done with care, and by exception. If the VPN doesn't work on well-known Websites, it's not exactly ... useful. 😥

All of a sudden I am finding that Firefox will not connect me to certain websites such as Walmart, Doordash and even Firefox itself. It looks like it's trying to but it just gets stuck. What's causing this and how do I fix it?

Hi Team,

Since yesterday I am observing the issue while accessing Whatsapp which is asking for Quick security check with passkey and same was observed in Google which was resolved within few clicks but not Morzilla.

Currently using with Google.

Recently (within the last month, March 2026) when pasting links into emails on Microsoft Outlook online a pop-up window appears which prevents you from continuing typing unless you manually click on the window with your mouse cursor (hitting enter isn't sufficient). This is extremely aggravating and significantly slows down workflow. As far as I can tell, this issue only happens in Microsoft Outlook. I have ensured my Outlook settings aren't to blame, in part by failing to recreate this issue in Google Chrome and Microsoft Edge on the same account with the same Outlook settings.

Here is a screen capture of this happening I recorded tonight: https://imgur.com/Qte3N6b

I have ensured my Firefox is up-to-date (Version 149.0.2 64-bit).

It looks like others have had similar issues. Some examples follow.

1: /u/TyDraniu reports this issue on Google Docs here: https://support.mozilla.org/en-US/questions/1567972. (I do not have this issue on Google Docs, only Outlook.)

2: A year ago a reddit user reported this issue and a config altering "fix" that a Mozilla engineer said was very bad advice: https://old.reddit.com/r/firefox/comments/1dofgd2/pasting_into_web_outlook_popping_up_little_paste/. (I have not tried this fix given the engineer's response.)

3: That reddit post links to a 2023 Mozilla Support thread noting that same "fix" but containing no actual solution: https://support.mozilla.org/mk/questions/1411533#answer-1579497.

I would like to make the toolbar and bookmark font larger. When I search for answer it keeps telling me to change layout.css.devPixelsPerPx to a larger number. I have done that a couple of times, and after restarting Firefox the font is still the same size. I search the community and didn't see an answer either, so figured I would ask. Thanks Jack

I installed a new hard drive into my computer and when I downloaded firefox again none of my saved links, passwords, themes, etc. moved over even though I signed into my account. Please help! Asap!

When I went to https://www.mozilla.org/en-US/products/vpn/ and decided to purchase a Mozilla VPN prepaid annual subscription part of the reason was this "feature"

"Easy Firefox integration with the Mozilla VPN extension (Windows only)"

There is nothing easy when clicking on the download for the Mozilla VPN extension yields a message that the add-on or extension has been blocked. The explanatory link provided is https://support.mozilla.org/en-US/kb/add-ons-cause-issues-are-on-blocklist. That lets you know that:

"When add-ons violate Mozilla’s policies, compromise user safety or privacy, or fail to meet user expectations, Mozilla takes action. This may include disabling add-ons in Firefox to maintain a secure and reliable user experience. "

So, when will Mozilla stop violating Mozilla's policies so that the Mozilla VPN add-on is fit for use on Firefox v 149.0 [without free VPN] running on WIN10 64?

Сегодня обновил Mozilla FireFox до версии 146.0 (64-разрядный). После обновления в панели "закладки" (cntrl+B) появился ненужный мне цвет выделения только что открытой мною вкладки (смотри скриншот). Как поменять данный цвет на менее контрастный ? У меня включена "темная тема", цвет выделения - ядовито-голубой. Хочу изменить его на другой более мягкий цвет. Как это я могу сделать?

Today I updated Mozilla Firefox to version 146.0 (64-bit). After the update, the highlight color of the tab I just opened appeared in the bookmarks bar (Cntrl+B) in an unwanted way (see screenshot). How can I change this color to a less contrasting one? I have the "dark theme" enabled, and the highlight color is a bright blue. I want to change it to a softer color. How can I do this?
