When viewing email on Outlook in Firefox, there now appears a rectangular black box over part of every email. This does not occur when viewing Outlook emails on Chrome or Edge. I thought it might be because of my adblocker (Ublock Origin) so I turned it off, but the black rectangle still covers part of my messages (and I have Ublock on Chrome, too, with no problem viewing Outlook).

The rectangle covers only a portion of the messages. When I scroll the message, the black rectangle remains stationary and the message scrolls behind it, thus revealing the portion previously covered by the black rectangle (a different portion of the message becomes covered).

I tried to take a screenshot to show the black rectangle covering part of the message. Amazingly, even though the black rectangle is there when I take the screenshot, the screenshot itself does not display the black rectangle....instead the message appears in the screenshot without being partially covered by the black rectangle.

Hello there to all.. I have been experiencing occasional crashes on the tab when left idle for a while!! I am using Ubuntu linux 22.04 when this occurs..! In Windows 11 or even Windows 10 x64 pro this does not occur to my knowledge at all.. So I am wondering why this is happening only on ubuntu linux 22.04 and not anywhere else??.. Anyways, Thanks for listening and have a great day ahead also..

Crashes freeze ups Tired of them all day every day. Cache fills up and computer shuts down. 24 Firefox processes ,,, 37 Firefox processes and every one of them is storing history and cookies till the system stops.. Performance section? Worthless. Does not matter what is checked or unchecked,, and NEVER has there appeared a box to choose a limit of 6 or 8 processes.. WTF

So Firefox did an auto-update a few days ago, and when I opened the browser EVERYTHING was gone. Passwords, bookmarks, etc.

I've managed to get the old bookmarks moved over, but I cannot for the life of me figure out how to get the old passwords back. The old data is in a folder on my desktop, do I just copy and paste the login and key 4 files from that folder to the new folder?

Sorry if this seems like a dumb question, I'm a pleb and this is the first time I've experienced this. :(

I've been using Firefox 78ESR for Mac for quite some time, but finally decided to upgrade to stable release Firefox 99. What I discovered is that when I'm on a webpage and right-click and click on "select all" to copy all of the text, the text does not get copied. I have found this on websites and especially in blogger. I'm wondering if there's some setting I'm not aware of, or if Mozilla just completely did away with that ability.

ABC (Australia) https://iview.abc.net.au/ No longer plays video. It does on other browsers. I've followed FF advice ive come across by disabeling extentions/add ons, restarted FF but no luck. Also, I've started in safe mode. Also no luck.

Why is there now no option to close present tab only when clicking on X. The old (default) warning was excellent. With no warning, clicking the X kills Firefox - and all open tabs. This has lost me hours of work already. i certainly don't want to go down the route of restoring all tabs first. I can't rely on it, for instance, holding all comments made on a form. And for that matter, I wouldn't want that to reinstate a login.

Please can we return to the warning with 2 options Close all tabs and Close current tab only.

Many of my bookmarks are corrupted. They point to other websites, not the bookmarked one. Has anyone else had this problem? Is there a fix? Thanks for any info/advice. George

I cannot removed total adblock and especially the ad for total adblock. I tried to follow the instructions, but they do not bring up the menu that they are supposed to bring up. HELP

Each time Firefox updates, the email client changes to the outlook default. The last 2-3 updates, mailto does not appear on the file,settings,applications menu. Nor will it populate if I type it in. I have tried every instruction to no avail. I am a long-time firefox user, non-techie and it is discouraging when things disappear with each update lately. Would appreciate any suggestions. Thanks

I use a program called Solver to generate reports and download them in the .xlsx format. After a recent update in Firefox, my downloaded files no longer contain an extension and instead only appear in my download folder as a generic "File".

I've checked and .xlsx files are definitely associated on my computer with Excel. Also when I open the file or later "Always Open Similar Files" they open using Excel no problem.

What's the reason these aren't getting an extension added to them? I've attached a picture where file 1 is what it looks like for a file downloaded using Firefox, file 2 is the same file that is opened at the time of download.

My issue kind of looks like this one and it seems the issue was a bug and the user needed to download a new release of Firefox: https://support.mozilla.org/en-US/questions/1277280

Hi,

In the parameters, I chose to let Firefox ask me every time what to do with PDF files. But, when the window pop up and I click "Open with ... Firefox", the browser download and open with Firefox the PDF instead of only showing it in Firefox. When I set the "Open with firefox" by default in the parameters, Firefox will this time directly open the PDF in the browser instead of downloading it.

Are you aware of this bug ? Is there a solution ?

Thank you very much !

On my old (Intel based) MacPro Zoho email works fine. On my new M1 chip MacPro when I first open Zoho, or open an email, the page does not render properly at first (buttons/links don't work etc). After a delay it refreshes and shows properly. The delay depends on how fast my internet is - in the evening it can be a minute or so. Even when the internet is good I still get 2 versions of a page with a pause in between.

I tried on Safari and it works fine - which makes me think this is a Firefox issue.

I have some screen shots but when I click the browse button below I can select a file then it just endlessly shows working. I will have to email these to you separately

Thanks Phil.

Why is firefox automatically downloading strange files I've never seen before? (MEUIVFJ-.htm and 3tHMwYhc) They look a little untrustworthy. My download dropdown suddenly showed me that one had been downloaded, and then a while later the other one was downloaded. Are these actual Mozilla files? Or are they some kind of scam/trojan/spyware? I just realized that two were downloaded last month as well.

hi,

My firefox is downloading all the adobe files even though i have turned of the auto download option. Also whenever any pdf file i try, it gives me an option of open with or save file. I am trying open with & firefox still downloads that file to my system. Can anyone help

Hi Firefox team,

First of all thanks for this amazing product.

I hope you are aware that drag and drop to Outlook 365 (online version) on Firefox browser v99.0.1 is not possible.

Regards,

I am trying to transfer my bookmarks, open tabs and passwords etc. from my old laptop to my new one. It appears I have to do this with Firefox Sync under the preferences menu. However when I try to connect a new device, I am told to open the code scanner on my Firefox App, which sounds like I have to use a mobile? How do I scan the QR code using my new laptop?

I wonder why the latest browser does not have a Home Button.It is easier to close the blank browser with the Home Button.Closing the blank browser helps the system restart smoothly in the next session.
