Hi, I’ve been experiencing slow startup times in Firefox, especially when I have my Time calculator web app open. The browser takes longer to load and sometimes becomes unresponsive.
I’ve tried disabling extensions and changing my home page, but the issue persists. Are there any specific settings or troubleshooting steps in Firefox that can help improve performance when using online calculators like this?
Any guidance or tips would be greatly appreciated. Thanks!

This is a brand new problem, for me. It just started today when using FireFox. On nearly all websites, including Mozilla support, when I click on an embedded link on a site, firefox asks me to select an app to open the https. Even if I tell it to let firefox open all https, it still asks me everytime. to make it better, it still doesn't always let me open the link and I go through the same thing when I click the link again.
This also happens when clicking on the search box in *any* search engine, e.g. Google, Startpage
See the image below.
I've attempted to change all cookie & tracking settings, no help. I even uninstalled and reinstalled Firefox.
This is making FireFox useless.
I had to use my default browser, Brave, just to submit this question. I only use FireFox for social media accounts, sites I need to link to my sm accounts and the occasional web search. For example, linking my Etsy shop to facebook. When I clicked the link "link to facebook" is when I noticed this problem.

Hi,
Looking at my Firefox 147.0.1 settings for macOS 26.2 (Apple M1), I'm trying to adjust two settings:
-- I'd like to remove Languages -> English (GB) (its existence has odd side effects, like triggering United Airlines to offer fares in Pounds Sterling, and I'd prefer to just have English (US))
-- I'd like to disable Play Audio and Video for about:welcome (in regular and private windows)
I can see no way to accomplish this currently -- why?
Thanks.

I have lost my tabs after the recent update. They used to show all tab groups in toolbar icon as mentioned here (https://support.mozilla.org/en-US/kb/tab-groups) in manage tabs section. Only the groups that were open are retained, the groups which were closed are lost. They contained important tabs which I haven't bookmarked. I didn't see any policy of removal of inactive tab groups after certain time, any help would be really appreciated. I use the desktop app on Linux.

This is the 3rd time I have had to post this. I am getting very frustrated. I DO NOT want the search engine within my address bar. Nothing anyone from you "community" helped to disable the search engine in my address bar. Opera, Edge, Chrome, the user can disable the search engine in the address bar. Why is Firefox so different? And difficult?

Recently, Firefox updated and ask me to setup a profile, which I have not yet done since importing my data from google chrome in 2025. After skipping the setup, Firefox then deleted all my data and it has since been irecoverable. I have already checked the box last update that specifically said to not ask me again for setting up my profile. After the recent update, the question popped up again and now I cannot recover my original profile, all my browsing history, all my browser-saved data, and all my cookies and logins
Pls clear this issue

Hello,
I have my browser startup settings set to 'open previous windows and tabs' However, every time I start up firefox, it is on the default new window screen rather than my previous tabs. This feels frustrating as I have to reopen the tabs every time.
Would it be possible to fix this?
Thank you.
