I'm a web developer and I've been using the web developer Responsive Design Mode for some testing.

Unfortunately the default resolution is 320x480 and while I do occasionally test this resolution (it's our bare minimal mobile resolution) it's obnoxious to have to always choose the drop down menu to change the resolution every-single-time!

I've already searched through about:config settings for queries such as 320 and 480 separately.

So: how do I change the Responsive Design Mode default resolution?

When trying to navigate to websites I very frequently receive the error message, "www.google.com. PR_END_OF_FILE_ERROR". (1) This is an intermittent behavior happening on websites that were accessible previously and then become accessible again on later attempts, (2) It happens on websites that I have used satisfactorily for years. (3) It happens on ones for hospitals, banks, etc. which are known to be secure. This occurs after waiting for a period of time, like a timeout error would. I do let my copy of Firefox do its default auto updates.

Please advise how to end these errors so that I can reliably use Firefox again.

Hi. Since FF v103 it seems, when working with a VPN, and then trying to use also a browser extension VPN, it either does not or does not connect until after 45s. Before it was immediate. It works in all other browsers (incl FF before v103). So this is a recent change in FF that harms normal VPN connections. I found out by trial and error, that changing the port of the VPN extension to 443 and disabling and enabling the extension and going back to v103 from v103.0.1 helped, but that should not be like that. So something has been broken in the latest v103.0.1 - please kindly look into it. Thank you!

Somehow when updating, AVG Antivirus has managed to install it's browser on my computer and it has taken over my Firefox downloads. I've tried everything the internet tells me to try and yet there it still is. Any ideas? Also, if I can get the browser uninstalled, I'm afraid I'll lose all the downloads it has stolen.

Thanks So Much!

When I right click on an image in Firefox, and choose the "Copy Image" option, it never works. In fact, it hasn't worked in years for me, and that's on numerous PCs, with Windows 7 and Windows 10. I'm doing this so I can paste images into Photoshop. It looks like, instead of copying the image itself, it's just copying the image file, but this means I can't paste it into Photoshop.

I have tried several ways without success. The server is being used as the master server in a Citrix environment and the users are expecting a near Windows 10 experience in their VDI. Any help would be appreciated

Hello! Sites like Gartic Phone and Whiteboard Fox do not respond to my Huion tablet pen. I don't think Firefox recognizes the pen as a drawing device.

I have done some troubleshooting and have figured out that this is a Firefox specific issue: Google Chrome and Microsoft Edge both respond to my pen on those sites. I saw another person was struggling with this exact same issue, but the thread was archived with no response.

How do I fix this? Was there something I missed in the settings?

I was having problems with WWF on FB a few days ago. I think it's their problem after I cleared my cache and temp files. But now Firefox won't recognize me and I have to log into all of my programs like it's the first time (i.e., Insta, LinkedIn, etc.)
