Diễn đàn hỗ trợ Firefox

I am trying to access a website which I used recently, but I keep getting the message "Disallowed key characters". why is this and what can be done about it? The website is http://www.sykescottages.co.uk

Logins and passwords are missing. Noticed this when websites that I commonly use were not auto filling. There must have been more than 100 entries in my Logins and passwords folder. Now only 25. This is on Windows and iphone where I use Firefox.

I have been using Firefox on my Huawei P29 for several years. I have Google UK set as my search engine and on my home page and this has been fine for years. Two or three days ago when I loaded Firefox Google UK and Google.com wouldn't display. The link flashes in the top bar but the page stays blank. They will load in Chrome and in Firefox if I have desk top mode switched on, but not in android mode. I have uninstalled and reinstalled Firefox, cleared the browser cache but no change. Getting pretty fed up with wasting my time sorting it out. Is it the Huawei phone or Firefox's last update?

Why does your Browser use up so much of my CPU & have all these unknown processes going without my knowledge??? It's slowing & unnecessarily overheating my gaming laptop! What can I do 2 kill all ths extra, unwarranted activity of your Browser?!? Plz help!?

Firefox will not open most websites, other browsers still open them. Current version of Firefox v121.0 64 bit. Problem started maybe 2 to 3 versions ago. At this point I cannot use Firefox at all, but I really prefer it to any other browser. Please let me know what I need to change in settings or Please repair Firefox soon.

Thank you

Firefox browser, Windows 11, window is minimized to task bar, and will not maximize to screen. Uninstalled and reinstalled, that worked for a few days. Drilled into profile, renamed xulstore.json. Worked for a couple of days. Did that again today, restarted, still cannot use Firefox. Will be forced to transition to Edge if I cannot stabilize Firefox.

its the browser, the opperative said when I phoned in about no access. try chrome, they said and true enough it worked. Just shy of 15 years with firefox and now nothing but problems, the cut and paste does not work and now this! pointless staying with them

When I followed instructions, it sent the login file to the flash drive I designated but in an Excel format & I don't know how to print it in a readable (.doc format). Any help is greatly appreciated. bucretired@yahoo.com

I need to pass a pc scan on my new hp all in one desktop for a new job with Arise.com It allows me to use mozilla firefoc for my pc scan, I continue to fail. please help

Up until today video on youtube played fine. Today I can hear audio, but the scree is just green. Trying to fix myself, I read change preferences in Fire Fox. But I can't figure it out. Bitchute and Rumble play fine. I reset my desktop by turning it off. Same with closing down my browser. No help there.

After years of Firefox, suddenly I cannot start Firefox. It crashes in less than 5 seconds after I try to open it. Safemode did not help. Reloading Firefox did not help. And I certainly need my bookmarks and history. I have no idea why it is suddenly happening. i am on a Dell Desktop, windows 10, 64-bit machine. Both Malware Bytes and Norton show there is no malware.

i now keep getting a pop up window saying that this profile was last used with a newer version of this application. Please create q new profile. what am I to do?

I recently noticed that fields on all Web sites I visit have an extra horizontal line at the top of the prompt. Please see attached image. This only happens on Firefox. Other browsers don't have that behavior. How can I restore the normal prompt of a straight vertical line?

Thank you!
