Firefox Community Forum

Hello, I have added quite a number of bookmarks to my Firefox app on my iPad. I’m set up for syncing to my iPhone. I’ve tapped sync now on my iPhone and on the iPad, but only a few of the bookmarks have synced to the iPhone. I’ve also shut down and rebooted both devices. Both are signed in via email and set up for syncing, so I’m at a loss as to what to do next. Does it just take time? Any advice? Thank you.

Recently transferred from Chrome. My understanding was Firefox private browsing was supposed to work similarly to chrome incognito mode; once you close the browser, all local files are deleted and cookies are cleared.

However, with Firefox it maintains my logins. If I log into an account while private browsing and the close the browser, I’ll still be logged in next time I go to the website even if it’s days later (and I have never logged into this account in a non-private browsing window!)

I never had this issue using chrome incognito, so it seems to be a Firefox problem.

Is this just not something Firefox supports? Is there any way to prevent storage of cookies and private data?

Is there away i can get my browser history and data back ,i logged out of windows couldnt remember my password ,logged in with a new password and all my data is gone .....

Hello, FF support forum,

I think I have seen a Container retain my login to a site when I open it again after closing it. Is there a way to configure Containers so that they are mini versions of the dump-cookies-temp-data when I close Firefox entirely? I would so love that functionality.

Regards, G.W.

Connectivity to www.xfinity.com disappeared...with latest firefox 140.0.4 as near as I can tell. xfinity still works on Google Chrome and Microsoft Edge. Please fix firefox browser so I don't have to go to chrome or edge. thanks!

When I click on a bookmark, FF opens it in the current tab, overwriting the site I had open. I have to add a tab, then click on the bookmark to have it in a new tab. This is an annoying extra step. How to I change it? I already tried the open links in new tabs instead of windows. Makes no difference On or Off

After my pc has been on for a while, seemingly random duration, Im not able to open firefox anymore. For example if clicking on a link in discord, or if I close the browser and want to open it again. I've tried refreshing and reinstalling but that didn't help.

In Windows 11 settings > personalization > composition, is a way to change sounds like: error sound, connect device etc.. Before Firefox I used chrome and I set a sound for minimizing/maximizing and it worked. Whenever I minimized the browser it would play a custom sound. Since I started using Firefox the sounds don't seem to work anymore. Now I know the sound still works because when I minimize/maximize the file explorer it plays the custom sound. Is it not supposed to work or is it a bug? How can I make it play the custom sound? Thanks in advance :) (In Windows 10 it didn't work aswell)

The problem (Firefox being slow) happens within the confines of Troubleshoot Mode, I have already attempted a restart as well as clearing all temporary cached files and pages to no avail. While I did manage to make it better through setting my proxy settings to 'No Proxy', Firefox still seems to be running at a slower pace than even the dreaded Chrome. Youtube is the worst offender, with videos that used to run smoothly in Chrome now lagging, buffering, and moving so slow that Youtube is forced to automatically reduce the video quality (however, I should note that even on 360p do I encounter a large amount of slowness). Please note that I am a total dummy when it comes to technical stuff, so I will most likely need extensive and comprehensive instructions on ways to solve/diagnose this issue. I thank anyone who's willing to help me with this, it's the only thing that Firefox is worse at in comparison with Chrome.

When I search for something in the address bar using Firefox, I don't receive Google suggestions. The second photo is from another browser and shows exactly what I want.

What settings might I have changed?

Firefox currently: https://prnt.sc/11K105eLPdle

I want: https://prnt.sc/ToJ_b2PQ14k9

Note:

   browser.search.suggest.enabled => true

   browser.urlbar.suggest.searches => true

I've looked at the details in the config. As above. I've also used the Firefox Reset feature, but the problem still persists.

Yesterday I synced Firefox desktop to iPhone 13 and iPad 11. I created an account. The syncing worked.

Today I tried to access one specific website and got this message: "500 server error. Oops. Sorry. Your request could not be carried out because of an error. Please log out and sign in again". That didn't work.

I tried accessing other websites within Firefox desktop Version # 140.04 64 bit. They do work.

I don't know if this service error is something within Firefox or within Windows 10 latest update, or something else. I've reviewed system Administrative Events and there are numerous notes for 7/18/25. Many say "Distributed COM" some are Service control manager, many entries "Device setup manager". I have photos of several screens.

I've deleted cache and history (I use private Mozilla). I've restarted the laptop PC twice. No change to that website access. I used troubleshooting and that didn't help at all.

Please help diagnose where the problem is and how to fix it if the source is my computer. If it's a server problem please advise. Thank you. JHL

I just installed Firefox 140.0.4 on my MacBook Pro, and the text size in the tab headings is way too small. I've seen fixes (from years ago) for older versions of Firefox, but they haven't worked for the recent version 140.0.4.
