I cannot access the Epson ET-2850 Drivers and Utilities Combo Package Installer since the time has expired.

I checked and the clock in my computer is accurate.

Can anyone please help me figure out why can't I access my multiple open Firefox tabs on my Widow 11 desktop unless I open a new tab, and then click on the three line Firefox app menu symbol, then select "History" and then go back? I don't even have to choose a function under "History". I just go back to the tabs and they have become available to be selected and activated. This fix is only temporary and may have to be repeated several times in one session. The misbehaving tabs show up in a horizontal row over my toolbar area (sometimes as dark panels after an update) but clicking on them just causes the row of tabs shown, or the vertical list of excessive multiple tabs, to disappear. I tried selecting troubleshoot mode, but did not see any indications of errors. This problem only began after my last Firefox update and does not go away after a Windows reboot.

I could not join a group panel discussion in US using Zoom. The error message said connection could not be made with a Zoom site ending with .us The meeting was organised by Coda a US based organisation. The Uk end was organised by a website called Eventbrite. I tried again using an I-Pad but got the same rejection withh error message PR_END_OF_FILE_ERROR

I should add that recently quite frequently when I start an online search on my Windows 10 PC a box appears at left end of search box stating   "Insecure" but this quickly disappears.

When i try to drag a text/word/link to between tabs (i generally have 10 tabs open) it opens a new tab at the far right. I tried to change "browser.tabs.insertAfterCurrent" but it just opens the new tab next to the tab that i'm viewing. For example, when i'm at the sixth tab and i want to open a new tab (by dragging) between third and fourth tabs it opens that tab on the far right. This wasn't like that before how can i change it?

I want to watch Survivor on cbs.com. I get error code 111. It will not load. Something is blocking. How do I unlock?

Is there any setting that allows to get rid from this annoying Titlebar (line with buttons) in fullscreen mode? So that it never shows up even when hovering the mouse pointer over the top edge of screen. When it jumps out everything slides down and always leads to miss clicks when I try to select tabs. I don't want it to be constantly present here as well because it takes up screen space.

Dear sir or madam,

Can you please help me with a deeply frustrating problem I'm having with Firefox? After the last update, the shortcuts on my FF homepage disappeared and I can't restore or rebuild them.

Under settings, the homepage is set to show two rows of shortcuts but none are visible. I changed it to show more rows, closed & restarted FF, but no shortcuts appear. I then changed it to no rows, closed & restarted FF, then set it back to two rows, closed & restarted FF - still no rows. I've tried starting FF in troubleshoot mode, but to no avail. Looking through the Community Forums, I can't find anything that directly relates to my problem. In case this may help, I've had this problem once or twice before but I'm afraid I can't remember how it was resolved or if it was anything I stumbled upon that fixed it.

The environment is FF version 136.0.2 (64-bit) on an Acer Aspire E5 PC running Windows 10 Home, 64-bit, version 22H2, last updated 16 March 2025.

If you can offer any suggestion how I can resolve this and stop me pulling my hair out (in my case, it's an endangered species!), my remaining hair and I will be eternally grateful.

Yours faithfully, Peter Palmer

Some time this year I noticed that when I get home from work and wake up my monitor (PC is always on and doesn't sleep or log out) I get an email notification in the bottom right corner for every email I received that day and it takes a couple of minutes to clear.

I don't remember this before, it was only live notifications in the bottom right as they came in, if you clicked the Windows notification icon it would show you all of the past notifications on the list of course.

I still want the notifications for live incoming mail but not all of the unread emails previously.

I don't know if this is a Firefox setting or a Windows one but I couldn't figure out how to change without disabling notifications all together.

I cannot install Adobe Acrobat. I believe it is because my computer is old.... I signed up for the account but will not be able to use it. I wish to uninstall...please

Hello, Win11 Pro 24H2 Firefox 136.0.2 (64-bit)

When I alt tab over to my firefox windows and then press ctrl t to open a new tab it does not work most of the time. I have to sit and hit the keys 10-20 times before it will allow me to open a new tab. Do you have any idea why this is happening? I have tried safe mode with firefox and the issue persists so it is definitely not any extension that I run.

I updated my FireFox. In the old version I have a list of bookmarks on the left side on my firefox home screen. In this new version I dont have that and can't see how to get it back. Can someone help. Also, when someone replies where do I see the reply?
