If I go on any website using OSM data (including OpenStreetMap itself) on Firefox logged into my account, I experience a lot of slowdown. This doesn't happen when I use incognito mode or when I use another browser, so I'm pretty sure there's some kind of cache or something that's connected to my Mozilla account that slows down OSM massively. I've tried clearing all cache and all cookies. I've even refreshed Firefox using the installer and it's still slow. I don't want to bother with deleting my account and creating a new one. What should I do to try and return back to normalcy on OSM?

On Galaxy 23 Ultra using Android 14 & Ui 6.1 w/ Firefox, my Bookmarks disappeared. How do I get them back? Tried about:profiles, but nothing comes up. Recently due screen going haywire, phone was reset & the shop left me with Google, which I hate. Have been things getting back to Firefox I've used for years. Not sure if lost then. Bookmarks screen/setup I get, must be Google's, because it's not like FF's. I have Samsung & Google backups, but didn't realize Bookmarks were not put in them. Phone & apps are kept updated. FYI if it matters: Due to storm damage, I'm without a computer that might help. Help, pls. I'd be very appreciative.

On Feb 13th I went to my website at MyHeritage.com, to which I'm always logged in, to find that a few seconds after it loads it becomes all greyed out and I can't access anything. I had been on the site a couple of weeks earlier with no problems.

I removed the "Enhanced Tracking Protection" and I turned off AdBlocker for the site but the problem persists. I have logged out and then logged in - same problem. I turned off my computer and restarted it - same problem.

When I went to log in to my account at MyHeritage using my Chrome browser I encountered the same problem of a greyed out page BUT there was a banner stating something about cookies and when I clicked the "I understand" button the greyed out page cleared and I was able to access my account.

However, Firefox is my default browser and I want to be able to access this page using Firefox. It seems to have something to do with cookies.

I recently downloaded Firefox on my Mac and am having an issue with a "Log in" button not being functional on a website (www.pressdemocrat.com).

A few details: I use uBlock Origin. I added a Firefox exception to allow pop-ups on the website. I cleared cookies and site data I disabled extensions and still had the problem I created a new test profile with no extensions and still had the problem It works on other browsers

The Subscribe and eEdition buttons work on the same website, which is extra-annoying.

Last update Version: 135.0.1 (64 bit) Since I upgraded, all cloudflare robot verifications are not passing. It constantly redirects to the verification page. For this reason, I started using a different browser. I go in and test it from time to time, it is still the same. Update. Fix it.

Note: I reset the browser. I removed the add-ons. I reset the proxy. Cache was cleared.

Result: It still does not pass cloudflare verifications.

google search said this is Firefox intertnet speedtest app or extension but the actual descriptions says it's not monitored?? does firefox have a secure internet speedtest? why are these blank?? We've made some educated guesses about your current browser and operating system

is this support or forum??

After using Mozilla / Firefox for at least 30 years everything I had saved, bookmarks, history, passwords, shortcuts, are all gone! I need them back ASAP. I have a Mozilla recovery key but cannot find in all your articles, where to enter it. Please explain to me where to enter the key and why after all these years everything I have accumulated is gone.

So i have an odd question, something went awry after relatively recent update and my Firefox is not even bothering to display preferred 2 rows of links on new tab.

i basically use them as extended bookmarks in more convenient placement. as i have too many bookmarks

new install of firefox won't load accounts.firefox.com

other browsers on the computer load it fine

I've imported bookmarks and passwords and stuff, and since refreshed firefox but can't find a way to fully restore it to initial settings, even uninstall and reinstall won't do it

does Firefox no longer support sites like The Guardian, like the Atlantic, other news outlets. it never lets me sign in but returns to the home page after signing in with email and password. What do I do?

I was trying to fix a problem with eBay where I was unable to send a message to a seller. (A problem I have since discovered had nothing to do with Firefox it has to do with eBay). I had asked GPTchat for suggestions and it had me open a terminal and run some commands (don't remember what it was). while running this command we lost power and since then I cannot resize a Firefox window. However other windows like Dolphin or LibreOffice are unaffected. All else appears to run fine

After upgrading FF to 135.0.1 it always fails giving me this error: Gah. Your tab just crashed. We can help! Choose Restore This Tab or Restore All Crashed Tabs to reload the page/pages.

I opened closed it, rebooted, different urls. Firefox doesnt work at all. I had to use Chrome to ask this question.

An error msg that starts with (GAH)!! is this for real?

I have been block since yesterday afternoon on Mozilla to use this Etsy.com. I have reset history and cache per Etsy and it would work once after signing on and then it would block me. Now I have to use Chrome to get access to my account. I need to have this break in service fix for Mozilla/Firefox. Privacy and security is important to me. Thanks
