command shift ~ (to switch firefox windows) does not work with FF 148.0.2 (aarch64), MACOS 26.3.1 (25D2128)

Hello, I accidentally clicked on a new toggle button and it opened a Google sidebar. I also now do not have the ability to have multiple tabs open on the same browser. If I clcik on command-T (Mac), the screen goes dark. What happened? Can I get my old system back, without this Google sidebar?

Last week I downloaded the latest update for Firefox. After that I could not open websites I often use, such as etsy.com and ebay.com where I sell items. Also could not connect to Firefox Support. Yesterday, 4/19/2026 I uninstalled and reinstalled Firefox. I have box selected to open new tabs instead of new window, however, when I click on a line from my email it opens new window which causes me to have to sign-in to my accounts again, multiple times today. Also, after the latest update I cannot use my main modem network, have to use another wifi network. Also a couple of times today when I open a tab it is trying to use the primary network and pages will not load. I need help in resolving issues caused from last weeks update. I know this is very long but felt I need to tell you what is happening so you'd better understand steps to take to resolve issues. Thanks for your help.

Since the update I performed today, 4/27/26, I am unable to upload files to my NAS via the Firefox web browser on a Windows 11 PC. I can still do it via the Google Chrome browser so I am not completely crippled, but it would be nice if I could still use Firefox for this work. Any suggestions on how to fix this, or will it require the software itself to be fixed?

I have a Mac Pro laptop. Firefox has been my default browser. I never had problems accessing websites before, but now, suddenly, I get a rejection notice that prevents me from using certain websites and even links in emails. I am 74 years old and not technically mobile or able to figure out how to correct the rejection notices I receive. You have no phone number or other way to reach you. I have looked and tried to find where the problem may be but I have been unsuccessful. I have no idea if it is an accessibility problem or a connectivity problem . As well, the fonts on any instructions you provide are almost impossible to read as they were written for midget eyes. I would be grateful if you could assist me and send many thanks.

I had recently tried to download a .Zip file, which got corrupted. I tried twice again. Now every time I open the browser the three corrupted files pop up in the "downloads" window. It does not appear when opening a new tab, only when starting the browser. I have deleted the corrupted folders and don't want to retry downloading. I have tried both "clear all downloads" and "remove from history" in the downloads window, but the notification still shows up. Settings do not help.

How can I remove this pop-up? It blocks my toolbar and is a general nuisance.

bold textI have used Firefox for several years and it is the only browser I have on my Win 11 PC I just purchases and installed Malwarebytes Premium now I get the attached screen on banking and other daily used sites that never open When I un-install Malwarebytes software everything returns to normal Do you have any updates that correct this issue Malwarebytes recommends not using Firefox

Since about mid january, the language of documents at my homebank, is switched from the original danish langguage, to english. With Google Chrome browser, it is still danish. See attached scree print. Left originl danish, right - strange - english. As far as I have found out, there was a SW update of Firefox late January, that could have introduced this fault. I have had contact to Homebank supporter, of course. Their first question was: Switch to danish langue. But is is, as it has been foir several years. Please help me! Also I have some other minor problems, as many homepages do not test changes with Firefox. I do not want to list it here! So I ask you to make less special SW for Firefox, otherwise you will lose many users. It is NOT OK as it is.

I play the on-line KY lottery on a regular basis on my computer. As of late I am getting a message that states we cannot validate your location when I attempt to play games...ie. powerball, pick 3 and pick 4 etc. I had no problems until the last few weeks. I can play on my phone but I don't like to play on my phone.

I tried to add the KY lottery to the location permission area under the Privacy and Security settings. It will not accept it. I know at one time several website that I use used to be in the location permissions and now they're gone and I can still use the sites.

Confused and not sure what to do.

Thank you,

I use Brave, Firefox, Firefox Developer Edition and Thunderbird. Brave: 600mb Firefox Dev: 600mb Thunderbird: 200mb Firefox: 800mb Why is Firefox using too much memory? Especially as I am running Firefox Dev as a direct comparison. I don't have any plugins on Firefox. Firefox Dev has uBlock Origin alone. Brave has a few plugins.

I've disabled HTTPS only mode. When i enter a local http://server.localdomain server Firefox upgrades that to https://server.localdomain. How do I disable that?
