On fresh Firefox install that I setup using [https://mozilla.github.io/policy-temp.../#preferences|preferences] Which is option to disable those default ads?

Namely: twitter, youtube, facebook, Wikipedia and reddit.

I know I can do it manually with 5 x 2 clicks but that's 10 click every time I install browser.

Image showing YouTube as example what I want to get rid of.

I use firefox on my windows laptop and on my ipad. I had set up bookmark syncing so that I could access the same bookmarks on both my laptop and ipad. At first it worked! But today I added some new folders and bookmarks and despite checking that the syncing had happened the new bookmarks added on my ipad are not visible on my laptop - what can I do to fix this?

I need to use one website that has an out of date certificate. I found out about adding the hostname to security.tls.insecure_fallback_hosts in about:config.

However, Firefox keeps clearing that setting when I'm not looking, sometimes in the same session! How can I make it persist?

There are websites that I go on that require verification codes. After entering the code I check the box to remember this device. So then the next time I go on the website I would not have to deal with a verification code. I've used Firefox for years and had no problem with the browser not remembering an approved website but now I'm experiencing this problem.

I can log in to my BT emails using Firefox, & they appear on the screen, but are 'greyed out' & I can't read them or do anything with them. To read them, I have to use Microsoft Edge as my browser.

I'm using Firefox v115.15.0esr because I'm using Windows 7. I'm in the UK. Every now and then I get to a website which asks about cookies permissions and then proceeds to give me a huge list, hundreds of alleged companies which have a "legitimate interest" in me having their cookie, which I have to individually search through and deselect. Is there a way around this please? Does firefox ignore/prevent the cookies under the "Enhanced Tracking Protection" policy? or by accepting them do I still get them? I have ticked "Delete cookies and site data when Firefox is closed" so am I correct to assume that all cookies that make it to my PC get erased anyway when I close the browser?

I have a situation where I constantly have to send tabs from mobile Firefox to desktop Firefox. So I use Send tab to device feature. But when sending, manually clicking on the Synchronise now button in the Account menu of the toolbar of the receiving device is often needed, or else it would take a while for the tabs to be received. But I find that annoying and unintuitive.

Is there a solution for it? For instance, syncing Firefox devices more often, maybe just for the sending tabs feature because sync-now also syncs history, and bookmarks.

Hey everyone,

I'm having a frustrating issue with Mozilla Firefox on my Intel-powered laptop. Every time I try to use Firefox, it crashes randomly, especially when I'm loading multiple tabs or watching videos. I'm running the latest version of Firefox, Version 130.0 and my laptop is using an Intel laptop https://www.lenovo.com/au/en/faqs/intel/best-intel-processor-laptops/ i7 processor with 8GB of RAM.

I've tried some basic troubleshooting like clearing cache, disabling add-ons, and updating drivers, but the issue keeps happening. My laptop runs everything else just fine, and other browsers like Chrome work without any issues. I'm not sure if it’s a Firefox bug or something specific to my system. Has anyone else faced this issue with Firefox on an Intel machine? Any suggestions on how to resolve this? I would appreciate any help or advice on what to try next! Thanks in advance!

I changed my hardware and reinstalled Firefox. I signed-in using the same google account but my search history and saved passwords are now lost. I need them back. What should i do?

Often I can't access content indicated by a link in an article or email. I tried turning off the Firefox firewall, but it made no difference. Now I am unable to turn the firewall back on.

Every time I have to restart the microsoft nightmare called windows 10, the 1st time I open Firefox it opens in a half screen window on the right side of my screen. It's set to open maximized and run as administrator but still won't do so immediately after a restart. Is there a fix for this?

Hey, I just recently started using Firefox, and I've started to notice some odd behavior. When watching videos and reels on Facebook (Desktop version), videos will flip-flop between normal and really bright and washed-out. I'm currently on Firefox 130.0 on Windows 11, and I always have HDR on. The imagery is silly, but these two screenshots (using win-shift-s) are from the same video only seconds apart, and this happens on almost all of them. Not yet tested to see if it also happens on Youtube or Twitter videos.

I have changed my settings in Firefox to have Firefox the default when computer opens but it still opens with MSN which I don't want. Every time I go into settings even after re-boot it still shows to start with MSN . I change it again and same thing over and over.

thanks for any help and I have a feeling I have to delete firefox and re-install but worried all my links and bookmarks ect will go away.

After upgrading my Mac to Sonoma, Firefox quit working. It gets stuck on checking for updates. I have searched the web for answers and I have:

Changed my proxy settings - made no difference Opened in trouble shooting mode - no difference Deleted all cache etc - no difference Re-installed Firefox - no difference Set up a new profile (multiple times) - no difference Reset Firefox (multiple times) - no difference Ran a check for Malware - none found A few other things - no difference Firefox has been my main browser for about 15 years and it is now useless. Please let me know if there is a fix. I hate using Safari but I have spent days on this.

thanks
