Firefox Support Forum

Hello,

I've had an ongoing problem that I've been ignoring, but today it was hard to ignore. I hope someone can help me.

Some webpages load with code where the buttons should be. I've included a screen shot.

I'm running FF 78.11 on a 2011 MacBook Pro with OSX 10.12.

Steps I've taken to try and fix the problem: - emptied the cache - turned off all privacy extensions independent of one another: ADP, Privacy Badger, Ghostery, Enhanced Tracking Protection and AdGuard - restarted with adons disabled

These steps didn't work.

The pages load with no problems on Chrome and Ghostery Dawn.

What is the problem here, and what can I do to fix it?

Thanks in advance for your help.

Folks frequently bemoan that Firefox doesn't have the same Ctrl+Shift+T keyboard shortcut to Restore Previous Sessions that Chromium has (heck, I'm one of them), but I noticed that Ctrl+Shift+N will restore Previously Closed Windows. From a backend perspective, is there a functional difference between these two options? Does using the Restore Previous Sessions button in the History panel behave differently in regards to, I don't know, cookies or something? I'm a little hazy on what a "session" is and why it's important.

Hello, I'm running Firefox 78 on fresh Debian Stable installation and I cannot access certain websites. I followed step-by-step the instructions by Mozilla Support found here, with no result. Of course, I tried completely uninstalling and reinstalling Firefox, renaming .mozilla folder to create a new settings folder, deleting .cache/mozilla etc. I use no proxy, and I can visit all those certain websites form other browsers of this installation. And I'm looking for a solution for more than 2 weeks now. Any help is welcome!

We are receiving this message from Ebay when attempting to list a product (see below). Any suggestions how to work around it please? Thank you.

Did Not Connect: Potential Security Issue

Firefox detected a potential security threat and did not continue to scgi.ebay.co.uk because this website requires a secure connection.

What can you do about it?

scgi.ebay.co.uk has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.

The issue is most likely with the website, and there is nothing you can do to resolve it. You can notify the website’s administrator about the problem.

All my other applications and browser apps show a "toolbar", the uppermost edge of my screen, with "Firefox" and bookmarks, etc. It is just gone. I can't figure out why it is not showing up or available. I am not in full screen mode, although that hides the bar on top also. Mac OS 10.11.6, preferences says latest available update, although I cant tell because I can't set the "About" Firefox button.

Hello,

I just read an article from CIRA (Canadian Internet Registration Authority), dated July 8, 2021: https://www.cira.ca/blog/canadian-shield/mozilla-firefox-cira-canadian-shield?utm_source=newsletter&utm_medium=organic-email&utm_campaign=FY21&utm_content=the-dot-11

In it, they write, "Mozilla is enabling CIRA Canadian Shield as the default trusted recursive resolver (TRR) for Canadian Firefox users." I'm such a user. I also know *just* enough about the vast electronic highway system called the "Internet" to know I need safety and security measures in place.

I'm using FF 78.12 on MacOS Sierra.

I thought I'd see if CIRA Canadian Shield was the default proxy by going to Preferences > General > Network Settings. "Enable DNS over HTTPS" is selected, and the default provider is "Cloudflare." I clicked the drop down menu to see if CIRA Canadian Shield was offered as a selection. Alas, it is not. So, I selected "Custom" and typed in "CIRA Canadian Shield" (without quotation marks) and pressed "OK."

My questions are:

1) Is Mozilla enabling CIRA Canadian Shield by default as suggested in the article? 2) If so, why is it not indicated in the drop down menu? 3) Have I enabled CIRA Canadian Shield by typing it in the name as a custom proxy server?

Thank you for your help in advance. Please note, I have a rudimentary understanding of how this all works, so your simplified and somewhat non-technical answers are appreciated.

I need to Change my primary email address on my Firefox Account. HOWEVER, my old MAIN email address is defunct. The servers have been shut down & I no longer have access to it. I have my secondary email attached but it will not let me change it without sending a code to my old email. PLEASE HELP!

My firefox version is 78.9-esr As attachment, Japanese and Chinese character will be messed up. I have tried to install different fonts like fonts-arphic-ukai and fonts-arphic-uming, but it still displays improperly. By the way, it can displays Japanese and Chinese in html correctly.

Greetings,

I just updated to Firefox 78.15.Oesr and now am unable to reorder my open windows. As a student, I may have several projects open at a given time, and like to have the project I am currently working on, next to the open Firefox window, for quick navigation between the browser and project. This option seems to have been disabled with the update. It is enough of a deal breaker that I may pursue reverting to the previous version of Firefox.

Also, the inability to delete bookmarks, and to close the bookmark window after selecting "show all bookmarks," remains a persistent frustration that I am surprised has not been addressed. With so many browser options available, these subtle annoyances are enough to prompt me to again shop around for alternatives, after being a Firefox devotee for over 10 years.

Thank you for your help, Josh Baker

I need to clear my dns for a website. I type about:networking#dns. I get the hostname list but there is no clear dns cache button. I was told there would be a button. How do I clear the dns for that website if there is no button?

Hi,

I think I broke the ALT keyup events in some way, probably with my configuration but not sure how.

If I put this code in the console : `document.addEventListener("keyup", e=>console.log('alt: '+e.altKey+' | '+String.fromCharCode(e.which).toLowerCase()));` and the press the keys, I have the following results:

- pressing "I", I get the expected "alt: false | i" - pressing "ALT+I", I get "alt: true | �"

I do not have the problem with other modifier keys like CTRL

Until sometime around earlier this year, I was able to use "Import bookmarks from HTML" between different PCs/laptops, and it would always restore everything flawlessly from that backup file: all folders intact, and every single bookmark in the exact order it's been for about 14 years.

But now, whenever I use the Import feature, all folders are flattened/emptied and everything goes into alphabetical order. No matter what I do, they will not load in my uniquely crafted order (based on the sidebar, which I use exclusively). Everything goes into a single unmanageable lump in Bookmarks Menu.

Restoring from JSON makes no difference.

Versions tested from 78ESR all the way to 91. At one point, I went back to 88 and it worked fine for a day or two, but then didn't.

By fixing the very first option you come across as soon as you go into General Under "Startup" The setting called "Restore previous Session"

Usually, a checkbox, is a boolean ON OFF.

Once more, this leaks data. For instance, logging into my webmail rebooting the machine, next time i launch firefox it spawns the same session again. This contradicts with the very first option under "General" -> Startup

If this was a public machine, some one would now have access to my email.

It seems that this is OS specific. But really, i don't care. My complaint stays the same. The option is broken, and firefox leaks data therefor. I no longer trust Firefox. This sort of stuff is not done deliberately.

Once more. perhaps bit logic is too complicated for you UI designers and a quantum gyro is more to your liking? Cause this is NOT normal.

Hello together,

when implementing canvas graphics with 2D context, I notified that the latest FF 87.0 on windows is much slower than chrome/edge/opera on windows and also much slower as safari on mac. I drilled into detail and detected that it was caused when drawing polygons with color gradient (see attached image). Means that using canvascontext.createLinearGradient() instead of flat colors makes it slow. On the other hand using flat colors is perfectly fast.

I wondered, because I had much better experience with FF and installed an earlier version (78.9.0esr) on the same windows workstation and the problem was gone. Seams, that some change made the newer FF slower with this type of graphic..

CPU is i7 8650U 1.90 - 2.11 GHZ, OS is Windows 10 version 20H2

But the effect is the same on all windows workstations I tested. Would be happy to see, that I can use FF again with these type of graphic apps.

We are running FF ESR 78.14.0. I see that ESR 91.1 is now out. I have seen this article on Firefox ESR release cycle, but not able to find out what the schedule is (ie overlap) for 78 and 91 releases. I am trying to do some upgrade planning. I expect 91.2 will auto upgrade and like to know how soon, otherwise I may need to manual update machines.

It would be nice if this page could be kept up to date for the relevant releases.

Driving the question is a specific issue with QuickBooks Payments not working in 78, which I am assuming has to do with something they consider obsolete security wise.

DISCLAIMER: THIS HAS BEEN SOLVED! Dear Firefox Team, I have installed Firefox-ESR on my HP Chromebook 11, using linux. I saw it going slow so I searched up stuff. I went to "whatsmybrowser.org", saying Firefox 78. I saw that on an article there is 91 and 95. It is 11/3/21, and no update is showing up which a help article said "On 11/2/21, users can update to Firefox-ESR version 91." I couldn't update, so I am now asking for help. Its also going VERY SLOW which I can barely run scratch, google, and even the homepage. Please give me answers so I can fix the problem. Thanks, cogithedog.

Hi,

I found some discussion related (https://discourse.mozilla.org/t/disable-add-ons-on-specific-website/33693) but no solution yet.

This is imho a big flaw in the privacy of users.

There are trivial cases, for example if I use a YouTube downloader plugin, I obviously want it to monitor my browsing ONLY when I'm on youtube.com...

And there are some critical cases: when I browse my web banking, or when I go on some trading website, I don't want my financial operations to be at risk because of an add-on that is very useful everywhere but on those site.

However, I don't want to exclude all the add-ons for those website too, that would be just too much.

I think there's already a coding base in place, since you can disable each add-on when using private windows. This could be enhanced by having a system of whitelist/blacklist instead. And this feature would actually make more sense than using a private window.

Another way would be to have this feature on per container, instead of per website, than would work well too.

People have different activities, and some requires useful plugins, that are very specific. I mean Keepass's add-on (for example) is useful everywhere, but many add-ons are related to one activity at a time.

For example, if I'm a marketer and want to analyze website, I'll use add-ons for having stats on metadata or keywords or even real time reports from Alexa or from AliExpress, etc...

But when I'm reading my email, I'm not happy those add-ons can see my data.

That would be tedious to disable all those plugins every time I change activity, especially since we are productive humans so obviously we need to alternate those activities doing multitask all the time.

And the private window option is not flexible enough for that kind of multitasking, when containers are.

I hope this helps everyone understand clearly why I think my request is not only a real user need, but also currently a flaw in users privacy since most people will not trade the comfort of their add-ons for some privacy concern they don't always understand...

I know this is some kind of feature request more than ask for help, but https://qsurvey.mozilla.com/s3/FirefoxInput/ is out of service so I don't know where to address my concern here.

Thanks for helping me pushing this idea forward.
