First, is there a list of commandline options?

Second, I would like to be able to start Firefox with a specified URL from a batch file -or- a .net program. Then, either close FF -or- switch to a different URL. is this possible?

I'm unable to log in to Telephone Service Co. - TSC Wapakoneta, Ohio website using Firefox, but Internet Explorer logs in OK. TSC Customer Service indicated problem was in Firefox, but Firefox seems to work OK on other sites. TSC suggested I clear cache & cookies. Is this a good idea? If so, how do I do that?

Hi. I am trying to get into chase.com web without success. Why I already try several download with different browsers.

I still have windows 8.1. I do all my bill paying online. I can no longer open my banks website for online business. I thought Firefox had renewed support through 2026? Wasnt Firefox a search engine? The listed search s - none of them open banks etc.

I'm trying to disable the alt + t shortcut in firefox and having absolutely no luck. I've searched for answers and all of the ones I've found haven't worked. I tried the about:config "ui.key.menuAccessKeyFocuses" set to true option and hiding the menu bar. Neither work. Is there anything that would work for me?

Hello. My tablet, has limited memory, due to its age. I am now finding that one of the main reasons why it is so slow is because whenever I open firefox, it opens multiple firefox processes which drain the memory and in some cases crashes the system. I have followed all the advice given to reduce these multiple processes, however nothing seems to work and at least 6-8 firefox processes open each time I open it. I have unchecked the recommended performance settings as well as hardware acceleration boxes. However, I cannot find where to set the content process limit to 1. Please tell me how to do this and if there anything else I can try to stop it opening multiple processes or I may be forced to ditch Firefox altogether for an alternate such as Bing, Chrome or DuckDuckGo. Many thanks. Charlie

A few times now, I have inadvertently opened a second Firefox window. The original Firefox window comes up with two pinned tabs. If I close the original window then when I start Firefox the next time, it no longer has pinned tabs. I am running Win8.1 on a desktop system.

I tried accessing Peacock but was told they only support version 127+. I checked my version is 115.xxx but says browser is up to date. What is going on?
