Diễn đàn hỗ trợ Firefox

This lasts possibly 3 seconds. It has an email logo and a high pitched sound. It just flashes on, not long enough to read, just long enough to be annoying. The location is always on the Top Right corner of the display. I have all notifications and web push blocked in Firefox preferences. System is Mac, OS 12.1

cannot open allmusic.com website anymore on firefox. this website opens fine on other browsers. Only Firefox is the problem. Any suggestions?

I may have inadvertantly blocked Firefox from executing. I run Windows 11 on my desktop, and use SpyBot as my virus defender. Last night SpyBot may have run and prevented Firefox from running. This morning it would not open at all, no matter using a shortcut button or activating the program directly from Menu. I tried re-installing, but a window opens saying, "Hmm. For some reason we could not install Firefox." I tried uninstalling Mozilla but the window opens to initiate the process but in 20 minutes less than 1% of the procedure bar is lit and blinking. Do you have any suggestions?

Every website I try to visit with Firefox produces a page which reads "Suspected Phishing." And when I click on "Ignore and proceed" I am taken to a blank webpage. Each web address in the URL field reads "SmartDirect.de." Firefox has thus, for me, become a useless browser.

Is there anything I can do to fix this problem with Firefox? In answering my question please bear in mind I do not have a PhD from MIT and am not an expert in computer science.

When I log into my modem it sends me a banner notification my "version of Mozilla Firefox is unsupported. Your gateway's web interface has been tested to work with a minimum version of 63.0.3. You may proceed with an unsupported version." However, when I am in my browser, and select Help--> About Firefox--> it shows I am on version 136.0.4 and up to date. When I access my modem, why does my modem say my browser is out of date when it isn't? Does my modem have a different browser version from my computer, and if so, how do I update that? Thanks in advance for any guidance.
