Firefox Support Forum

Today, out of the blue, my email screen adjusted itself to be very, very tiny. I almost need a magnifier to read it! I cannot find how to put it back to normal!

Please help!

For some time, I’ve been using characters like em spaces (U+2003, or ‘ ’), thin spaces (U+2009, or ' ’), and hair spaces (U+200A, or ‘ ’) on my webpages, and up until a few revisions ago, Firefox was displaying them appropriately. Rather abruptly, they were replaced with boxes.

This doesn’t appear to be a font problem; it happens with every font, including several that I’ve verified have the character in question. (In the image below, it’s in Times Roman, but I’ve tried Noto Sans, Arno Pro, and half a dozen others.)

Does anyone know why this is happening, and does anyone know a workaround?

When I want to do a google search, it will only do an amazon search. So if I am asking a tax question, it brings up amazon products to buy. I can't search anything. Very frustrated.

I need some tips and tricks to generate an HTML email that will actually function with reasonable reliability without my having to wade through troubleshooting and correcting for the myriad problems that might and do cause it to fail because of issues with the Windows operating system, Thunderbird Add-ons and extensions, and Third Party apps that interact with shared system hardware/software resources in ways that can, and do cause failures.

The two parts to the question are: Given that I have the source code for a simple W3 compliant Web Page with internal links that renders properly in Firefox, what is the most efficient way to embed that functionality into a Thunderbird email? and

Is there any chance that it will render properly and function in the delivered email on email clients (including T-bird).

I've just spent three hours trying to find an answer stating the question as simple and as many different ways as I can.

I've struck out completely, the second strike being Mozilla support where the closest I came was a query that returned two options, one referring to doing something on the T-bird console; the other providing instructions for how to disable pop-ups in the browser, which appears to be one of the primary things that interferes with the functionality.

They were understandable, but haven't the referenced resources used them regularly in years, am not familiar with them. and am too damned old to have the patience to screw around with them.

Strike three was composing much longer request on this form and losing it. I don't remember how I did it, but when I was in the business with own web servers the standard practice was to design the web site so that the content of forms was persistent. That's ingrained, and my forgetter works to good.

Any tips or tricks will be appreciated.

I recently changed to Firefox from chrome and the focus on security and privacy was a much needed upgrade. However, every time I close my windows I'm logged out of all my accounts. I checked all the settings that would have that effect even escalating it to a clean install and unfortunately nothing works. After checking the support forums this setting seemed to be the one that fixed things, attached is a screenshot showing that its unchecked and that there is cookie data stored, so I'm really at a loss.

I am developing an extension that will fix YouTube spacebar issue (after recent YouTube update after Alt Tabbing from other window, spacebar is not working to Pause/Play videos).

The problem is that my extension is not working anywhere except on https://www.mozilla.org.

I've already added "*://*.youtube.com/*" to "host_permissions" in my manifest.json file and it's displayed as "Can always read and change data on this site" on YouTube, but it does nothing. On https://www.mozilla.org my extension is activating properly (writes test message in console).

I added my extension on "about:debugging". Can it be related with that? Appreciate any help!

When I export the data I get three date/time fields with numbers in exponential notation that will not covert to a date in MS Excel, e.g., "1.50931E+12" What am I doing wrong?

Hello. I'm using Firefox 119 for MAC OS. However my device is labeled as Windows 10 Firefox. I don't have any Windows software labeled anywhere. I have signed out, restarted device and still no change. When I log into a website from Firefox, my "authorized device" is recognized as Windows Firefox.

Please advise, Thank you

4 PM, November 7, 2023 EST. The "About" page of all YouTube channels suddenly disappeared, whatever the the login status. A compressed version will show up from a channel's home page when clicking on the site description from its Home page. Make things weirder, ~6:15 PM it WAS visible from the Tor browser but started acting the same. I have no ad blockers, or ANY extension installed on any apps, including Firefox/TOR browsers. Updates to both browsers were made prior to this behavior. It may be Google/YouTube's fault but it's becoming frustrating because I prefer Mozilla's browsers over Edge or Chrome.

Every time I close my Firefox browser, the same tabs are restored after reopening the browser. I don't want that to happen. How can I get them to close completely? I'd still like the option to restore the tabs but not every time.

Hello, I have been getting a bit annoyed at something very small that I tried to fix, but nothing I do is working.

I am wanting to use the address/search bar and click my mouse wheel to open a new tab in the background. Without switching to the newly created tab. But instead it's always switching to the new tab right as I click with my mouse wheel.

I have tried looking up the problem online and following the people's advice on other posts. Nothing is working to change this. At all.

I went to the "about:config" area and tried switching a few settings related to opening the tab in background and restarting Firefox, I tried going to the actual setting page and the checkbox for "When you open ... switch to it immediately" was unchecked. Nothing was changing at all and clicking the mouse wheel was still opening and switching automatically. (All "__inbackground" stuff in about:config is set to true at the time of this post, I have noticed that changing stuff in there and restarting Firefox isn't effecting/changing anything)

I would really appreciate some help if this is still able to be changed. I recently switched from Chrome to Firefox, and I really loved how I was able to click my mouse wheel to open a tab in the background. (Also, I am using the latest version of Firefox)

I am using Firefox for my emails and I can't now see some of the Unread Messages on my screen. My Firefox version seems to have changed and before it had a folder of Unread Messages and it still does but when I click on that word, it does not show the Unread Messages.. There are 8 messages there so how can I see them?

I used to be able to access my email with previous versions of Firefox but cannot anymore. When I attempt to sign in it just goes back to sign in page. I have to use another browser to access my email. Is it possible to go back to a previous version of firefox?

I have been a loyal Firefox user for many many years. I lost count. I have gone so far as to uninstall Edge from my computer. BUTTTTTTTTTTTTT. Your recent updates are leading me to switch over to Chrome. With your recent updates, I now have to run Firefox in trouble shooting mode in order to be able to access and make my payments in my PayPal account. It now completely messes up my PayPal screen. And, most recently, now I have to click to make a YouTube video play on initial launch. Each time I open a new video, it pauses and I have too click on it to make it play. AND, don't tell me to go check and set the "autoplay" settings. THAT DOES NOT work. So until you guys can show me how to revert back to a previous version of Firefox that worked.. I AM SWITCHING OVER TO CHROME. In my opinion... I consider what you have recently done to me is a VIRUS.. you broke something that worked.. Especially my PayPal stuff

Hi, I am seeing issues with autoscrolling in 119.0. In Rundeck for example you can "follow" the output of playbooks that are running so you can dynamically see the log as it is written. The autoscrolling in this field has stopped working. When manually scrolling in the field, more messages appear but the autoscrolling is no longer functional. I have also seen it on other places, though I don't have remember good examples to add, so I don't believe it is Rundeck causing the issue--we also haven't updated rundeck recently in our environment, so it shouldn't have changed since before 119.0 was released. Let me know if there is more information I can provide to diagnose the issue.

Since the last update (earlier this week) firefox uses large amounts of memory. It shows in the windows task manager 20 and more instances of firefox being open and one of them using 85%-90% of the available memory. I looked up help articles regarding this issue and one of them mentioned to "Delete content-prefs.sqlite file". When I do that it will help for a short period of time but then the issue is happening again. I'm using Windows 11 64 bit.

I'd appreciate some advice on how to deal with this.

When I followed instructions, it sent the login file to the flash drive I designated but in an Excel format & I don't know how to print it in a readable (.doc format). Any help is greatly appreciated. bucretired@yahoo.com

All downloads "fail" using Firefox. I have tried many things. Some on the internet says the fix is difficult. Other browsers have no issues with downloads. I go to them when I need to download something. I like Firefox, but if I can't resolve this issue, I may have to go to another browser. Help.
