Firefox Support Forum

Hi. I'm trying to download an installer .msi file from a valid link. If I do this in Chrome it simply pops it into the Downloads folder as it should. In Firefox, it downloads and then displays as a text page of garbage. It seems the file is wrongly defined as text/plain on the server rather than as a binary.

However, I've looked into my Firefox settings to see if I can define the handling behaviour of that file type. I can't! Amazingly to me, the .msi file type can not be added to the list manually. There is no "Add File Type" functionality in there. It seems as though I have to handle the file in Firefox for it to see that that type exists and then it will let me add it to the Downloads/Applications area of settings.

I can right click on the link and choose Save File As which gets round it, but then I still cannot see the .msi file type to add it to the Applications list. Can anyone tell me what I am missing here?

Moving mouse quickly and hit something, mouse clicked. BAM, fonts and picture to tiny size. Cannot find anything that makes that happen to undo it. All pages that site, no other site. Closing/opening Firefox stays the same. Zoomed to max and can now see, but page is not correct proportions.

Is there a toggle to turn off the purple theme in private windows? As an elderly person I find it hard to see things and it's quite irritating to say the least. This only started showing up in my Windows 10 and my linux systems in FF Version 106 and is also violating my preferences to have a totally blank page when a new private window is opened. Suggestions would be most appreciated.

Firefox view is a new feature that looks awesome and I'd love to try it out to sync stuff between devices. There's just one problem:

1. Firefox view works on my laptop and seems to work on my phone, but does not work on my desktop.

For reference:

• Desktop (doesn't have view tab) is Mac Mini 2020 (M1) on Mac OS Ventura 13.0 (22A380)
• Laptop (has view tab) is Mac Mini 2020 (M1) on Mac OS Ventura 13.0 (22A380)
• Both devices are running Firefox 106.0.2 (64-bit)

I have already:

• Made sure "Open Tabs" is enabled for sync on all devices
• Looked for the firefox view in the "Customize Toolbar" menu
• Disabled / Re-enabled Firefox-View in about:config

Hello

I am using Firefox for ARM64 Windows and noticed that the browser will lock up at random (roughly every half an hour, and usually after trying to navigate to a new page). As the browser doesn't actually crash, just freezes, I have no crash reports to submit.

I am using a Windows Devkit for ARM.

As a developer myself, my instinct tells me this could be an issue with Firefox's JIT for Arm64 platforms but I have no proof.

Hi, I'm migrating to a new PC and followed the below article to open all my currently synced tabs from the old machine on my new one: https://support.mozilla.org/bm/questions/1357426

The issue is that the on the new machine when I open all synced tabs, the order is reversed, i.e. my latest tabs that are on the right on the old machine are now on the left in my new machine. How do I tell open all tabs to keep the same order in the new machine? Any help is greatly appreciated..!

Thanks! manoja

Hi there!

I have a pretty frustrating issue with custom search engines. I use custom search engines all the time to look up words on a dictionary website. In cases where I need to look up something that is more than one word, I'm unable to use this feature because Firefox automatically adds '+' to encode spaces to the URL. since the website that I use does not know how to deal with that, I am unable to use this otherwise convenient feature in cases where my searches utilize spaces.

is this behavior adjustable in any way?

Firefox updated to 106.0.2 (64-bit). When I press ctrl-B, my bookmarks appear on the browser's left side as expected. However the text is not visible. If I hover my mouse over an icon is the list for a bookmark, the link appears. Also not all the bookmark icons appear. There are gaps between bookmarks on the list. Again, I have to hover my mouse over those gaps for bookmark info to appear. How do I make my bookmark list readable/usable again?

font corruption? the font called Calibri is showing up as italic in all websites that use calibri. but i dont have calibri installed on my computer. how do i fix this? in the past, my friend had a similar issue with fonts looking all weird in code on websites and i told her it was font corruption and had to remove a font on the system level which rectified the issue. but in my case, i dont have calibri installed on my computer. so when i go to the outlook website, all the emails are coming in as calibri italic out of nowhere, when i didnt change any font settings. if i go into google docs, and paste some notes and change all the notes to the font called calibri, it shows it as italic. but i dont have italic selected in google docs. how do i fix this in firefox???

MathJax formulas are not displayed correctly in Firefox browser windows, e.g. https://mail.google.com/mail/u/0/?ui=2&ik=96a0a80d2a&view=lg&permmsgid=msg-f%3A1748952987569305801&ser=1 Windows 10, Firefox 106.0.5 (64 bit) Thanks

I used Windows function to close all windows to close firefox. Big mistake. I had 4 windows open and for some reason, Firefox decides to only save 3. I lost my main window with a few hundred tabs open. I realized that when I opened firefox back up and immediately wanted to restore it using Recently Closed Windows, which usually works, but not this time, because it's been 4 windows. I backed up the sessionstore-backups folder but it seems like the "upgrade" files are too large for it to handle and the recovery files don't contain the missing window.

Help?

On Windows 11, latest version, lots of addons including tree-style-tab, so empty header tabs are in the file for my pinned tabs.

Hi, when I log into my bank I give my account number and then a password. I have told firefox not to remember my password but it is remembering the bank account number which automatically pops up when I am on the banks log in page. How do I stop this? Also when I signed up for this firefox help it asked for an email address and all my email addresses poped up for me to chose from. I didn't like this either. Appreciate any help. If these features can't be turned off whats the last version I can use that won't do this? cheers Neil

Dear Firefox Team, since updating, I've been enjoying the new Firefox View function. Sadly, as I'm using a few tweaks here and there (vertical tree tabs, modified chrome.css to remove horizontal tabs, etc.), its not visible at the place where it originally belongs. Because of that I'm searching for a way to include it in my workflow. To do this, I've made it my Homepage, and now, I'm trying to change it to my NewTab page as well. I find it more useful than clicking on a random website. I have tried to achieve this with addons and inside about:config; but as you know, "about:newtaburl" has been removed a long time ago.

Do you have an Idea how I could achieve this, or do you think it would be possible to create an option to this in a future release?

Thank you for reading my message, who knows maybe I can give you an Idea

All my bookmarks have disappeared from bookmarks. I restored bookmarks in the menu folder but my bookmarks in the bookmarks toolbar are still missing. How can I get my bookmarks in my bookmarks toolbar back?

Is it possible to request a feature for Firefox called "Link to Highlight"?

Chromium based browsers have a feature where you can make a selection of text on a webpage and in the right click context menu select: "Copy link to highlight", which copies a link to the webpage, with an appended selection like so: "#:~:text=Steps%20to%20reproduce%20the%20issue%3A". Then when the link is clicked, the Chromium based browser would scroll down to the match of the text, flash a colour to show where it is, and tint the text with a subtle highlight. The text in this example would then be "Steps to reproduce the issue.". This helps in my workflow when using a browser, so this feature would make me super happy.

I can't understand why the Windows menu shows us all the open windows, in no order whatsoever. Not chronological or alphabetical, just random placements, making finding anything a dizzying & time consuming experience, as I have to look up and down each & every time. I don't know of any other browser that gives no option as to how to sort this lis.

I've been unable to play twitter videos at all. For videos and audio posts on other sites, there's usually a delay for a couple seconds before it plays. I disabled all my add-ons and it made no difference. If I try to play 2 different things at once, both of them will chug if play at all.

Does anyone know what the cause might be? I tested videos and audio in another browser and they work fine.
