Firefox Support Forum

For a few months now, on different sites, the backround is fully black on black text and I can't use it at all, so I have to enter on Chrome to use it. I tried reseting the cache and booting in safe mode, but it doesn't seem to work. I changed things like themes and made the site be able to choose its own, but nothing seems to work. One option I found online but I'm not to happy to try is to make another profile, but I have all my passwords and bookmarks on this profile.

I have a question about the way Firefox browsers behave from a PC to an Android device. I have a simple non responsive HTML CSS website that I have built that looks good on a Windows PC browser but on my Android devices the layout is slightly off. I have tried a few tricks to solve the issue by adding a bit of length to a page so I could space out the text boxes and the links but it didn't help. The best way to describe this is to let you see a couple of snapshots so someone can see the actual issue first-hand. I normally test my websites on two different browsers with the other browser being Chrome. I test both on PC and Android and the issue is only showing up on Android devices. I am a Firefox user but I still test across a few different browsers to see how a website will behave. As mentioned, I only see this issue with Firefox on my Android devices and I have not been able to solve this issue. I would like to ask you if you can advise me on this issue. Thank you, Mike

Do I need an Firefox Update???

Thanks for your help,

PC

When I open firefox for the first time or after reboot or logout the internet doesn't connect immediately and it need almost 1 minute or more. I tried so many solutions, but they didn't work. If I reset Firefox, then the problem is fixed, but after some days, it's the same problem.

I use my new tab page frequently. But when I try to delete from history it does not work. How can I clear these to make room for more? Also, some sites are added after one visit but ones I use daily do not show.

I have a website that is now being blocked for 1 week jgonzalez@lungdoctors.com this is my Pulmonary Doctor

and have used this web site for at least 1 year. Being a novice I refreshed my Firefox site and now I have

Pocket which I do not want.

Any ideas would be appreciated very much.

Thank you Judith B. Basch

All of a sudden when I open a link from an email it opens on Edge instead of Firefox, even though Firefox is my default browser. Can you please tell me where I can change the automatic setting? Thank you, Maria

‘I can't receive outlook mail today using Firefox. I receive message header but when I open it there's no message data. It works fine in Chrome. I can't forward a message it fails to connect to the server. When I try to delete messages it doesn't remove the item. Any suggestions?

I have to press the F11 key to see the menus, scroll bars, taskbar, etc but the screen then goes back to full-screen mode.

How do I prevent full-screen ?

I have a local only test ca and test web server. How do I load the CA certificate into Firefox. Adding it via "settings" did not work, the browser says Adding a root via "settings" does nothing. When I access a web server it says "the original certificate provided by the server is untrusted", in the issuer name field. It never actually shows the certificate. Adding a file to the appdata area (this is on windows 10) also fails; changing the enterprise ca settings does not work. This used to work.

I have been using the "Restore Previous Session Option" fairly often for years, but within the last few weeks the option is no longer there.

I had tried to use the Settings > Open Previous Windows and Tabs as a workaround, but it doesn't appear to be consistent.

Did something change in a recent update, or is my installation broken somehow? I tried refreshing Firefox but that didn't bring it back.

The article here shows what I am referring to and has a screenshot of where the "Restore Previous Session" option was: https://support.mozilla.org/en-US/kb/restore-previous-session#w_when-session-restore-occurs

Anyone else have this problem? Is my installation broken? And how to fix?

Just today (2-13-24) I discovered that certain functions of Outlook (web based) do not work in Firefox. All functions do work in Edge browser. Windows 10, Home version. I can read my emails but cannot delete them. I also cannot delete Junk Email and probably others, but I've not attempted others. When I try to delete Junk emails, it seems that they are deleted, as they disappear temporarily from the folder, only to reappear after leaving the Junk folder and returning to it.

Looking for possible solutions.

New computer, new Firefox install. Old computer has the Library Icon in the upper right corner when the browser opens. I imported my bookmarks, but can't figure out how to get the Library Icon positioned.

When I try to open a new tab, the dot continues to move back and forth but does not load the tab. Sometimes I have gotten the message: "A web page is slowing down your browser. To stop it close the page."

I have tried fixes suggested on the web, but no help, including clearing the cache.

Thank you in advance.

I have Firefox installed on my Windows 11 laptop. When I click on a new tab, I want that new tab to show 4 rows of icons of sites I have visited most frequently like my bank, Amazon, etc. I do not know how to set a new tab to show the 4 rows of icons. These icons show up in Firefox on my Windows 10 desktop computer but not on Windows 11 laptop.
