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

The release notes for version 106.0 say: It is now possible to edit PDFs: including writing text, drawing, and adding signatures. [1]

But I see no button or other way to add a signature to the PDF I am viewing.

So, how to do it?

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

I am so fed up losing my pinned tabs.

I want a Firefox facility where I can have permanently pinned(locked tabs) and normal pinned tabs.

The permanent ones must not be able to be removed without myself physically clicking and removing them individually and are persistent when opening new browser instances, cannot be cleaned/removed by other cleaner programs are not saved in History.

Permanently pinned tabs should show a mark on the tab like a red padlock.

I use One Tab, but that has it's down side in that it clears my Tabs from the browser in to one single tab and then it is difficult to manage them, there are others and they all have their failings.

Please provide this locked tab facility.

Firefox version 106.0.1 Windows 11pro. Youtube videos will not play, unless they are Live. Weird. Checked internet. Loads on phone, loads fine in Edge. Restarted FF, cleared cache and cookies, tried private browsing, started in troubleshoot mode with no addons-- even the ad video at the top won't play. What else am I missing? Why will the live videos play but not the others? That seems like a clue, but I've hit the end of my ideas. I was able to watch youtube two days ago, the only change (afaik) is a Firefox update this morning.

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.

Firefox instructions for creating an electronic signature tell you to go to "Options" in the "tools" list, which I assume is the list under the three parallel lines in the upper right corner. There is no "Options" section in this list on my browser, either by itself or under one of the other categories in the list, or anywhere else that I can find on the browser website. So I can make no progress. Suggestions?

When installing Firefox, there is an option to import data from another browser. That feature is also available in the "Library -> Import and Backup -> Import data from Another Browser", and it imports things like Bookmarks and History from another browsers.

As the functionality already exists, is it possible to use that functionality in any way to import Bookmarks and History from a different profile in the same Firefox installation? I want to merge 2 different browsing history (like the old question https://support.mozilla.org/en-US/questions/928204), and looks like using the "Import data from Another Browser" could help if it's possible to use it with another Firefox profile/directory.

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.

How can I get certain bookmark folders from a backup json file ? I don't want to restore everything.

For example my Work bookmarks don't need to be same as home bookmarks, but I may need some of them. I can't copy paste each one manually.

Thanks in advance

i use the same add-ons on my desktop and laptop. i open my laptop and click on synchronize and later i open my desktop. two of these add-ons on the desktop have disappeared! this is not the first time. what can do i, how can install it to prevent it does not happen again?

I have tried both Google Authenticator and Guardian for use with Mozilla 2FA. I have tried scanning the QR code on my PC multiple times on each authentication app and retrieving multiple codes each time, but all entries stated "incorrect 6 digit code" on my PC to enable 2FA. I am not sure how this is not working. Both authenticator apps identified my correct login email address associated with my Mozilla account so I know it must have something to do with whatever is happening on the back end at Mozilla for my account.

Also, I have read a few posts in the Mozilla support knowledgebase regarding this very same issue, but did not see any resolution. I would really like to have 2FA. Can someone please contact me about this?
