Diễn đàn hỗ trợ Firefox

My address line is red, and their is an icon which say: browser is under remote control, reason: DevTools.

I am not sure how to fix this, or what to do about this. I do not know if I caused this myself. Please let me know if anybody can help.

I have to curate and compile sheets of announcements for a local humanitarian service provider forum. I do this by sifting through my Office 365 emails, and double clicking those that contain announcements so they open a window, then sorting the windows on a second screen, then read them, summarize them, file the pertinent information with links for my summaries, and when I get a page of them, send them out. I usually start with about 15 announcements on my other screen, and it takes me some time to get them all sorted and cascaded in order for the curation.

Some of them link to PDFs which Office 365 doesn't always preview and I click download, and this used to open them in the main browser window in a new tab, where I could read them and then save them. Recently, this behavior changed and they now open right in the window the email is in, with no bars of any kind or tabs to get out of them again. I hit the stack of pancakes button, and it had a tab marked Exit, so I thought that would exit me from the view.

Instead, counterintuitively, it exited me completely from FireFox, closing all of my carefully cascaded windows of announcements, and my main browser window with Office 365 in it and everything else.

Thanks a bunch. 1) What was so wrong with the previous setup that you needed to change it? 2) How for the love of whatever the author of this new "feature" was smoking, do I get it to revert to the email or is opening these attachments by "download" no longer possible without punting the whole thing to exit? 3) Does this mean I need to permanently disallow Firefox as the browser for all my PDFs or is there some way of doing something non-fatal to my work on a per-boot basis?

Why, with not very many active open windows, and just after opening, is FF using 175% of my CPU, not counting all the separate listings in my Activity Monitor. Plus it's using nearly all 16 GBs of my RAM. With every new update, I pray it will mean the browser will just work, and not use up all my computer's resources, but it just never does. Pretty soon, more & more of us will just give up on this browser, which used to work better, years ago, and has only gone downhill since.

The Firefox prefs.js file was quarantined by avast yesterday. Message indicated malware had infected the file. Now when I click on the Firefox icon the MSN browser comes up. How can I get back to using Firefox safely? Can I uninstall Firefox, then re-install it to make the problem go away?

Certain site show what looks to be Chinese writing in the menu and description. Videos for those site will not play. This just happen today. Is there something going on with firefox? what would be the best fix?

The behavior of FireFox saving PDF files has changed. I am using WIN10, FireFox 98.0.1 and have it setup to use windows default application and always ask where to save for PDFs.

BEFORE the problem: The PDF opens in Acrobat Pro IX. After clicking save I would be asked, where to save. I select the location to save the PDF. Then after this, subsequent PDFs downloaded would be saved to the last saved location. This process would repeat for a new website PDF load and save. This is the behavior I want now.

NOW with the problem: The PDF opens in Acrobat Pro IX. 1. Immediately, after a reboot, the save icon on Adobe is grayed out. I select save as and point to the desired directory. 2. For any subsequent PDF opened, the Adobe save icon is available. Files are saved to the desktop.

Please note I believe I once did get a popup asking where to save and I know I selected desktop.  Since that selection I am no longer asked where to save.

Please note I have looked and tried some of the suggestions at: https://support.mozilla.org/en-US/kb/cant-download-or-save-files#w_choose-a-different-download-folder

but some of this advice needs to be updated for the new FireFox version--ex no JSON file is found at the file location covered in the advice.

I believe this issue started after the last FireFox update. Please help me restore behavior listed above under “BEFORE the problem”. Thanks.

Firefox is steadily being unusable for me. On numerous occasions websites fail to show log in pop ups etc which work without issue in Chrome. Latest example : https://www.gog.com/en/games Clicking "Sign in" should show a pop up to allow me to sign in. In Firefox this does not show. I thought it may be a "pop-up" issue, so deselected "Block pop-up windows" in settings. Still the same. I added the website as an exception and still the same. Anyone have any ideas what is going on ? TIA, ZTB

The root problem is that when I try to open a movie in a web browser, I get the message "Oops. Your web browser is no longer supported. " see attached.

1370719 had a response that made no sense to me.

Is there anyway to fix this issue?

When I open Facebook with Firefox all of the images in the FB session are blank, and they will not open in the usual manner. Also only about 1/4 of the FB session is displayed.

When I use Edge I have no problems at all, so I have to assume that it is FF and not my computer that is at fault.
Please advise.

On Microsoft Edge, whenever i type the first letter of a word it will suggest automatically the recent words that i have use. How to enable it on Firefox, i already browse the settings? I really need it on my job specially doing reports. We can only use Firefox to access our websites.

Is there any to make Firefox automatically restart a new session (loading the start page) after a crash, without any prompts?

Context: This is for a disabled person who cannot use input devices: I start her computer every morning before going to work and load a long Youtube playlist of videos, so she doesn't have to do anything. But if Firefox crashes 5 minutes after I left, she cannot restart anything herself and has to wait until I come back.

Any ideas?

The Motherboard on my Windows 7 gave up, however the SSD that it was on is still working properly.

I have seen it on an alternative Windows 7 computer.

I specifically wish to recover the the Bookmarks that is on the Mozilla Firefox browser, and also all of my emails on Mozilla Thunderbird.

I would be most grateful, if someone can please tell me how this can be done?

I have loved being a Mozilla-stuff user intermittently since teaching on Netscape 1.1, and now am making Firefox 98.02 my default browser. I like both Safari and Firefox, and sometimes use them simultaneously for two accounts on the same service (not right now). My physically pristine 2015 Mac cannot install OS's past the 10.12 I have, so Safari is failing. But I am exasperated at runarounds when trying to set up this Firefox account. I used the emailed verification code and seemed to get in, but got the red-box message "This account... administrator... error." I cannot tell whether the site is letting me use it normally, but I think not. I just spent an hour in help forums. Geesh, tech complexity has mushroomed since my LAN work in the 90s, and you volunteers get to cope with inarticulate queries like mine! Upload is failing of jpg screen shot that has been made anonymous. Help?

When I try to download a file, the download always fails. This happens no matter what website I'm downloading the file from (see screenshot 1).

This started happening within the last week or so. We are running versions 97 and above.

Firefox is configured to always ask where to save files to (see screenshot 2).

Write permissions to the user's Downloads folder is denied for reasons unrelated to this issue (see screenshot 3). When I re-enable write permissions, the problem goes away.

Has anyone else run into this problem? Is write access to the Downloads folder required now, even if Firefox is not configured to save files to that location? Thanks!

Using firefox in linux mint 19.3 mate. Until firefox 97, I could control the size and color of the firefox scrollbars with a system CSS. Since a firefox update to version 98, firefox ignores those settings. Nothing has changed in my firefox settings, my about:config, or system settings. But now the scrollbars are barely visible low contrast narrow bars that are unpleasant to work with, and I can't figure out how to change this. suggestions? tnx
