This problem appears on MacOS 10.13.3 but NOT Linux Mint 19.3 (Tricia).

Repeat-by:

1. Start here:

       https://www.cnn.com/

That page should load cleanly.

2. Now click on "Live Updates", which is the top entry in the middle column of that page, and as of 3 April 2022 11:20 AM EDT takes you to:

       https://www.cnn.com/europe/live-news/ukraine-russia-putin-news-04-3-22/index.html

On MacOS, that page loads and is momentarily visible; then the page/tab it's loaded in goes blank. On Linux, that page loads as expected and remains visible.

Notes:

The problem did not happen with Firefox 88.0.1/MacOS.

The problem does not happen with Firefox 98.0.2/Linux, i.e., it appears to be specific to MacOS.

The problem remains whether extensions are enable or disabled (one a time or all at once).

The problem remains after the cache has been flushed and pages have been reloaded.

The problem remains after Firefox has been (completely) shut down and (cleanly) restarted.

The problem does not happen with Chrome/Chromium on either MacOS or Linux.

The problem also happens on *some* other pages on CNN's site (but not all) and on *some* (but not all) pages of other sites but there doesn't seem to be a pattern that explains which URLs exhibit it and which don't. This suggests that it's not privacy settings or extensions or anything like that, because there's no reason for those to vary from page to page within any one site.

If I'm VERY fast on hitting the "X" that stops a page loading/rendering while in progress, and I get the timing just right, I can catch it before the page/tab goes blank. So it appears that Firefox is in fact fetching all the content and can render it, but then for some reason is blanking the page/tab once that's done.

The attached screenshot shows what the problematic page (from step 2 above) looks like on Linux. On MacOS it's blank, so I didn't include a screenshot of that.

We got an alert when opening Firefox on our iMac yesterday suggesting we "refresh" and that bookmarks and saved passwords would not be affected. After the refresh, bookmarks were retained but all passwords wiped out. Further, as we painstakingly looked up or created new passwords on sites and entered them, the usual Firefox alert would come up asking if we wanted to save the new log-in, user name and password on each site, we'd select "yes" and then find none of them saved. Can anyone advise us? We're rebuilding our saved passwords on Chrome now but have had Firefox as out primary browser for over a decade.

Why why why why is FF forcing download of pdf files? It is a horrible problem for me.

Especially because I am a university prof and, in the classroom, constantly display (my own!) files from the course management system on the classroom devices. I DO NOT WANT MY FILES SAVED ONTO THE (PUBLIC) CLASSROOM DEVICE. Never mind multiple copies as it will download EACH AND EVERY TIME I open it.

I have been looking everywhere for a solution or a way to disable this feature, there seems to be no such option but I am seeing a lot of posts from people who object to this as much as I do.

After many many years of loyally using FF and a paid subscriber to some Mozilla services, I am afraid I am going to have to give up using FF is this isn't fixed NOW.

Before version 98 of Firefox, it would remember where I downloaded files to based on what site I'm downloading the file from. For example: when I would download a statement PDF from American Express, the Firefox download prompt would automatically be navigated to <...documents\records\AmEx\statements>. Then, when I would go to download something like the latest Firefox installer, the download prompt would automatically start in the folder <...programs\standard programs\Firefox>. No navigation needed in either case. Now, with version 98, all Firefox can remember is the last place I downloaded to, with no memory of site context. (This includes sites I've been to more than once since the update to version 98.)

This was a very convenient, time-saving feature. Is there any way to restore this site-contextual memory of download directories?

(I tried searching through existing questions, but my apologies if I missed an existing question on this topic.)

Thank you!

I know Firefox recently changed some settings regarding automatic downloading of files, but I need to know how to stop Firefox from automatically downloading .pdf files that I view. Sometimes I just want to view a pdf without downloading the file. Firefox keeps automatically downloading the file, then after viewing it, I have to manually delete. I don't to do this! I just want to view the file and if I want to keep it, I'll save a copy. This is extremely annoying! Can I change the settings so that the file won't automatically save to my computer? Thanks

Hi , My main machine is a personal windows laptop. Firefox sync works fine and syncs all things including "all" my installed extensions . recently company issues me a macbook and on it when i install firefox and login my account for sync it syncs other things like bookmarks but does not sync all my extensions only a few of them.

I already tried multiple things like sync delibrately from windows and then pressing sync on mac or reinstalling firefox on mac . but its the same issue.

few of the extensions that are missing :

1. Auto Tab Discard
2. Download Manager (S3)
3. DownthemAll
4. Stylus ( very important for me)
5. Tab Session Manager (THE most important for me)
6. TamperMonkey ( Important)
7. (Temporary Containers)
8. uBlock Origin
9. Xkit Rewritten
10. Zoom Image

The Send Tab/Link to Device feature only works in one direction, from iOS to MacOS. iOS to iOS never receives, although the popup says it sent. I'm using Firefox 98 on MacOS and iOS. I have a Windows 10 PC which can't receive or send tabs/links as well but I'll limit it to the Apple devices for the moment.

Sync and notifications are enabled on Laptop, iPhone, and iPad. I've de-synced and re-synced each device separately and together. I've attempted to send between each device separately and all together.

Neither iOS device can receive tabs/links from one another, nor send to each other. Laptop can receive tabs/links from both iPhone and iPad, but not send to either.

Each time I re-sync an iOS device I get a notification on the Laptop saying that "this computer is now connected with Firefox iOS". But still nothing works.

I don't want the pdf to save to disk without my will when I open a pdf file from any website. Fire Fox saves the file first, then opens it for reading. How to change it? I want to read the pdf first and then decide what to do with it. This works similarly in Edge. FF is my main browser, I wouldn't want to change that, but I have too much garbage on my disk. every pdf is saved first, completely unnecessary.

I installed Rust on my laptop and want to browse to the documentation which is installed at file:///home/lochlann/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/share/doc/rust/html/intro.html. I try to open this in Firefox and this fails with the message: Access to the file was denied

The file at /home/lochlann/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/share/doc/rust/html/intro.html is not readable.

   It may have been removed, moved, or file permissions may be preventing access.

I have read permissions on the file. No matter, it fails. I try to open the file using Firefox and navigate the directory structure rather than typing in the location. The file opens in the browser, the location is listed as file:///run/user/1000/doc/1f137432/index.html. Can you explain to me why Firefox cannot render a file that is where i put it and has appropriate permissions yet can render the same file where I did not put it? I have always been a fan but this looks more like a virus than I am comfortable with.

I'm no longer able to a particular website: https://www. bdo.com.ph onFfirefox. However, I'm still able to do so on other browsers, specifically Chrome and Edge.

The error message I receive is:

"Secure Connection Failed

An error occurred during a connection to www.bdo.com.ph. PR_CONNECT_RESET_ERROR

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem.

Please assist.

For over a decade I've used FF, and when I download things (99% of the time from Yahoo) I set FF to "always ask" what to do with downloads. Suddenly that changed and it started downloading everything automatically to the Download Folder.

I went to options and changed everything back to "always ask."

FF does always ask... but... it ALSO still auto downloads to the Downloads Folder now.

And I can't figure out how to stop that.

Any help is appreciated.

I will start by saying that I have not opened my laptop since March of 2022. It is now November. I go to my Firefox browser like I always have in the past. It opens and does an update. It comes back and I notice that my bookmarks bar is gone. I go to the bookmarks tab and all of my bookmarks are gone. I have never had a "Firefox Profile" before until now. I had to create one to try to get help. How can I get those bookmarks back? I tried to use the troubleshooting option that is listed and it did not work for me. I have a very important account that was in my bookmarks that I need access to. Someone HELP?!

This just started happening and I'm not sure why.

I access my email via a browser. When i compose an email If I have a .ZIP file that contains a bunch of files. If I want to attach say file # 6 and File # 7 to the email I am composing I would open windows explorer, traverse to the ZIP file location and click on it so it opens in windows Explorer. Then I'd highlight the one or two files I wanted and I'd drag them to the email.

This would typically attach the the files but it no long works - I have a feeling it may be due to windows 98 I hear you guys changed (fixed) how files are processed.

This is awful I now must extract those files to hard disk (of if there's another contained ZIP file within its even more extracting) - I'll this makes so much work and if I forget to delete all the files I execrated I'll run out of space.

Is there I setting that I can set to make it work the way it used to - I don't want to learn another browser but this change has killed my poductivity

Hello,

I have been using Firefox for something specific for a long time now. I've noticed in a recent update having the ability to do what I need has ceased. If a Firefox window is covering another (or covered by another program) on the screen, the graphics of the background Firefox window no longer update. I run a software that needs to see these graphics in order to function properly.

Could you tell me which version this stopped working and if there are plans to reverse whatever change you made?

Thanks, Kyle
