Here's the error page I get from O'reilley Auto Parts when searching. (I don't get this error when on O'relley com, but ONLY when searching for a part and ONLY with Firefox on my desktop. This started just a few months ago. All ad blocks and U Block Origin are disabled):

I keep having trouble trying to play a video on YouTube. When I try and play a video on You Tube the video will simply not play or take forever to start playing. What can be done to fix the problem? Can someone help. Thank you.

I still have not had any improvement with tab crashes especially on sites containing videos. Lately, every time i go on Facebook and play a video reel, i stop the video and before i can return to my home page, the tab crashes. This browser has gotten worse rather than improving.

ONLY IN FIREFOX when I open Spider Solitaire there is an hotel video ALWAYS in the lower right corner - NOT WITH GOOGLE. I try to block it but no go. Here's the site. HOW DO I GET TO USE IT ON FIREFOX???? https://www.belovedhotels.com/cancun/beloved-playa-mujeres/?utm_source=dv360&utm_medium=paid_video&utm_campaign=brand_bpm_us&utm_content=dv360_brand_bpm_us_prs_video_proll_na_inm_varios_na_2301&utm_campaign_id=dv360_brand_bpm_us_prs_video_proll_na_inm_varios_na_2301&adfcd=1688589882.y96yaB5xY0Ck-ZWc2v4Iow.MjM2NjE4MywxODEzNzQx/

Contrast disappears when I klick 'Login' eg. on 'https://www.elektor.de/'; other browsers are ok. AdGuard on or off makes no difference. Kind Regards [removed email from public]

I've disabled all of my addons, cleared cache, and still youtube is broken for me. It works fine with Chrome still. Any ideas on how to fix? See attched screenshot.

i just upgraded firefox for Mac OS to 115.23.0esr (64-bit) and now I cannot log in to my bank account from this desktop. Safari works on the iPhone but I NEED FIREFOX ON THE DESKTOP IMAC (Sierra 10.12.6) There seems to be NO INFORMATION ON YOUR "ASK A QUESTION" PAGE ABOUT THE UPDATE

I just tried to open Firefox and got the message "The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem". DO NOT redirect to this link

https://support.mozilla.org/en-US/kb/fix-bookmarks-and-history-will-not-be-functional?as=u&utm_source=inproduct&redirectslug=The+bookmarks+and+history+system+will+not+be+functional&redirectlocale=en-US

It is useless. I tried to restore 3953 items from a previous back up and received the message "Unable to process the backup file".

I am not interested in hearing how to prevent this problem in the future, because obviously creating backups do not work.

How do I check to see if the problem was caused by security software, even though I have not added anything?

I won't show my account information but when I try to access Amtrak's Guest Rewards site it goes into a loop. First it asks for username & password and accepts that with no problem. Then it asks for the code it sends to my cell phone and accepts that. And then it just keeps reloading various pages until I kill it. This is the error message shown in the log, it's repeated over and over:

NS_ERROR_ILLEGAL_VALUE: Component returned failure code: 0x80070057 (NS_ERROR_ILLEGAL_VALUE) [nsIFaviconService.replaceFaviconDataFromDataURL]

   loadFavicon resource:///modules/PlacesUIUtils.sys.mjs:220

   setIconFromLink resource:///actors/LinkHandlerParent.sys.mjs:139
   receiveMessage resource:///actors/LinkHandlerParent.sys.mjs:60

I'm running under Mac OS 10.13.6 The site loads fine when I use Safari (version 13.1.2)

Thanks

Hi,

just for understanding:

Why can the Firefox source code (view-source) of a website be nearly three times the size compared with Chrome/Opera or when I save the Firefox source code marked and copied and then pasted and saved via an editor?

Example: Firefox 546,6 KiB Chrome/Opera 204,3 KiB via Editor 204,3 KiB (marked and copied Firefox source code)

Best

I am trying to upload a document on the Supreme Court portal (UK) but it won't work I am told because my browser has to allow pop ups and cookies. Where can I get Firefox to so allow?

when I do a search, starting today, the AI either hangs, returning nothing, or only partially works and then hangs. This is serious for me as the AI results have meant that I was getting much more from a search than I used to. I am using a Samsung laptop on W7. I updated the version to latest one 115.26.0, with no joy. Is it going to stay like this? If so I will move on. I support Mozilla with £. Thanks for your help. I am 80 now. When I was 40 I would have been in the thick of knowing all about Firefox (I was in technical IT then) but I'm now too old to keep up with all that.
