Firefox Community Forum

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 am getting an er00r massage saying 'voise calling is not supported on this browser' whil trying to makea call on fasebook massenger using firefox.i have airedy tried restarting the browser, but it didn`t work. please help me fix this."

Using Windows 11 and a recent version of Firefox, if I open a command prompt window and enter: C:\Users\Admin\Documents>"C:\Program Files\Mozilla Firefox Esr\firefox.exe" --help

I get nothing.

But it works if I add "| more": C:\Users\Admin\Documents>"C:\Program Files\Mozilla Firefox Esr\firefox.exe" --help | more Usage: C:\Program Files\Mozilla Firefox Esr\firefox.exe [ options ... ] [URL]

Can anyone explain why?

Is it possible to change Firefox so that it works without "| more"?

Note that the above was on my Windows 11 laptop, but I'm sending this from my Windows 7 desktop. None of the suggested topics were appropriate, so I selected the first one "Accessibility".

Updated Firefox today. Lost all bookmarks,history and downloads. No icon present in header tool bar. Tried search and recovery using all available information listed under 'HELP'. NO success. Past profile storage locations are non-existent. Did a restore point on computer/ no help. I'm using windows 7 so did an upgrade as noted in Firefox notice.

I've been using Firefox for years and would hate to change. Hope recovery is possible.

Thank you, David

Subject: "Refresh" How can I turn off the 'refresh function' when I am signed onto a session? I understand 'refresh' should work when I log off and later log back on. BUT, I find it VERY ANNOYING when 'refresh' (going back up to the 'very latest whatever') happens when I have merely stopped for a minute or so to completely read an article, or watch a short video. When that happens I cannot get 'back' to where I was because of all the 'new' stuff, even after 10 or more minutes of scrolling down as fast as I can.

 When the 'refresh' happens and I am no longer able to 'find my place', I log out and turn the computer off for several hours up to several days (which is probably better for me anyway).  Your sandbox, your rules, but there are other sandboxes I can play in, and will.

Dear People --- FIRST: I apologize for taking so ling. I had physical probs, that kept me from coming back. SECOND: I'm afraid that I can't solve this problem with the advice provided. There was a file mentioned [which slips my mind, and I can't look for it with out leaving this screen] that is supposed to be on my desk top. I couldn't find it, so things stopped there.

SO..... I'm reiterating my problem: I loaded an "update" to Firefox that was supposed to get around the obnoxious "THIS BROWSER IS NO LONGER SUPPORTED" message I'd get on certain web-sites [such as the Milwaukee Journal]. I never understood that, as I am careful to update programs, when the updates are available. SO: While I was on the Milwaukee Journal Site, I clicked on the "Firefox Update" that the Journal's site recommended. What happened was I got the Current Version, and LOST all of my add-ons. After problems I can't go into here, "The Cat's Back." Please advise whether I can get things back after this much time.

N.B.: I'm running Windows 10.

when I do a search, starting today, the AI either hangs, returning nothing, or only partially works and then hangs. This is serious for me as the AI results have meant that I was getting much more from a search than I used to. I am using a Samsung laptop on W7. I updated the version to latest one 115.26.0, with no joy. Is it going to stay like this? If so I will move on. I support Mozilla with £. Thanks for your help. I am 80 now. When I was 40 I would have been in the thick of knowing all about Firefox (I was in technical IT then) but I'm now too old to keep up with all that.
