One aspect of Firefox I value is the ability to customize headers and footers on printed webpages. This ability is important for my work.

I customized the headers and footers in the about:config interface according to advice posted [https://support.mozilla.org/en-US/que.../1323433|here].

Recently, these settings don't take effect when I print webpages to pdf. I've triple checked that the settings are correct, but every time I print, the header and footer remain in the Firefox default configuration. Inexplicably, my preferred settings do take effect if I set the destination to "Fax." All other destinations don't work.

Is there any way to make these settings work again? Sadly, this might be a dealbreaker for me if not.

I have a problem on Firefox ONLY with my Shopify website login. I was having a weird problem with captcha cycling over and over and with Shopify's help I've changed all my passwords, added various authentication steps, including adding Norton and their VPN on top of the Firefox VPN. During all this I noticed a user that is NOT ME on my Shopify login page. Shopify can't figure it out and asked me to uninstall and reinstall Firefox which I did today. Mind you, everything is completely fine and normal on Chrome. After the reinstall, that user was still there! I logged them out, reset my password, checked it in Chrome and logged back in on Firefox. The user is STILL THERE!

What triggered all this was a random email about my products where the to: was blank. I replied to see which address it went to, which turned out to be a personal address that IS NOT associated to my websites. I actually have 3 on Shopify but only 1 has been weird. That got me worried. So I contacted Shopify and then this user (not me) showed up as I was doing screenshots to send to Shopify via chat.

Also all the Norton scans say everything is clean.

I have spent over a week working with Shopify in various capacities and now they have asked for an insane amount of information to ensure I am who I say I am. In fact I got a second round today! I've supplied both sets of information.

Is there anyone on the Firefox side that could help me troubleshoot this....live...not in chat hopefully! Could it be a Firefox issue?

Hi I am trying to change the default homepage Firefox logo to my own, but i could find no tutorial on how to do that. I only found 7-9 year old posts, that did not work. So my question is: Is it possible to change the default firefox logo on the homepage to my own one, and if it is then how?

I know this has been asked before but I've looked through past instances and couldn't find a solution that still seems to work as of 2022. I need a way to disable certain built-in Firefox keyboard shortcuts. I recently switched from Chrome to Firefox but if I can't disable the ctrl+i and ctrl+b keyboard shortcuts I'm going to have to switch back. I use both very frequently for work, so their non-functionality in this browser is genuinely impacting my productivity and it's getting really frustrating.

For the last few weeks I keep getting this error message: An error occurred during a connection to ....... You are attempting to import a cert with the same issuer/serial as an existing cert, but that is not the same cert.

Error code: SEC_ERROR_REUSED_ISSUER_AND_SERIAL

It will suddenly happen for multiple sites that I have been connected to in the past, or new sites I try to open including support.mozilla.org. A solution is to clear my history and restart the browser. It only happens on my windows 10 laptop. I think happens when I have logged off or the device has slept and then firefox has restarted and opened previously open tabs. Other devices on the same network don't get effected.

I am running Firefox 100.0.2 64 bit and now after literally years of visiting https://www.metrobyt-mobile.com/ to pay my mobile bill every month, it won't open the page. [See image of error]. I have gone into settings | browser privacy and tried turning off blocking for cookies, tracking content, cryptominers, and fingerprinters. No difference. I have gone into Enhanced Tracking Protection and clicked on Manage Exceptions and it won't give me an option to add the website. The site opens normally in Chrome. I find the instructions for "What to do if a site seems broken", but there is no shield or broken shield next to the web site address to click on. [See second image].

Hi. I know my firefox account email: [email]@gmail.com and firefox account password: won't type it here, but i know it and have entered it successfully.

After i sign in, with the correct email and password, it states i need to access the verification code and enter it to use my firefox account. the problem is that i just reinstalled windows and the gmail password was autogenerated and stored within my firefox account. so in order for me to access my gmail to retrieve the verification code i need to access the passwords stored on my firefox account.

I have a number of autogenerated passwords related to my college assessments that are time sensitive. I need help with this urgently!

Thank you, Phillip Shields

Every time I log in or refresh outlook, I get an email ad for outlook upgrade. It is from microsoft, and can be opened as an email, but it is an ad and can't be blocked. These emails remain blocked with Brave, and I am running an ad blocker. Will mozilla update to remove these ads, or is there an ad blocker that works better with Mozilla. When I inspect it, the first line shows:-

'On my firefox browser, the bookmark toolbar disappeared and wans moved from the left margin. How do I get it back to the left margin and auto open on every tab?'

When opening History the column headers are there but no dates are shown in the Added and Last Modified columns. These columns are selected in Views and the listed web pages appear to be correctly sorted into Added date order. My browser is up to date an is 100.0.2 64 bit. Thanks

I changed approx 15 passwords in Chrome and I would like to import then into FF. I already have the old logins/passwords in FF. If I import them from Chrome will I end up with double entries or with they be over written with the updated passwords?

I used to sign in to my credit card through Elan Financial Services and then I would highlight my credit card, tell it the date range I needed to update to Quicken, and hit enter. a popup would give me the option of opening the file or to save the quicken file to my computer. I would select the option to open the file and it would update my register on Quicken. Now, I only get the option to save the file to my computer. On Microsoft Edge, I still get the choice to open or save the file. Why doesn't Firefox support the Open Function anymore. I use Firefox for everything, but now I have to remember to switch to Edge for this one important update. Is this a change in Firefox or something I have to deal with Elan on? Thanks for any help. --sgb

I see no way of doing this. You'd think there would be an ADD option somewhere in the search engine page. Instead it takes me to the Add-Ons page. https://addons.mozilla.org/en-CA/firefox/extensions/category/search-tools/ What has this got to do with adding a search engine to the browser? Must be a mistake.

Hello, Why does Firefox convert my mp4 files to 3gpp files when I download them from my personal Flickr account?? Chrome does not - they download perfectly when I download videos from my Flickr account using Chrome - so why can't I download them as mp4 files in Firefox???

Thank you for your assistance in solving this issue

In my Bookmarks Toolbar I have created a Folder, 'News' and placed it at extreme left, next to the 'Show Your Bookmarks'. By clicking on the 'News' Folder I can see and select any of my favorite Web news sites. Very handy. Today, however, when I clicked on the News folder my 73-year-old hand accidentally dragged the News folder on top of the 'Show Your Bookmarks' icon and the News folder disappeared !! I can't figure out where it went !! Help !!

When I connect to my home router via HTTPS I get a popup with the message “Invalid Encryption Key”. I tried using other installations of Firefox and I don't get this pop up. I then made a new Firefox profile on the same computer and did not get the popup. So it seemed like a Firefox "refresh" would be in order. But after the refresh the problem persists.

So how do I resolve this issue?

Firefox is the latest version running on a Mac.

When accessing my Google Drive on Firefox and opening a shared folder containing picture files, the files can only be downloaded, not previewed. This is the case for heic files (I am working on a PC; files were uploaded from an iPhone) and jpg files. The latter can be opened in Google Docs; the former can only be viewed using an outside app. In both cases, the files must be viewed outside the drive. The file previews appear (both on the icons and if the files are double clicked) when opened in Microsoft Edge.

Clicking the back button does not usually take me back to Google search results. When I do a Google search and click on one of the resulting links, it's often (but not always, oddly enough) as if I've opened the link in a new tab with no browsing history. I can continue to click on links and build the tab's history, but the oldest url in the tab history is the one I got to after the Google search results page. To get to the Google page, I have to open my full browsing history.

If it's just my problem, I'll just keep doing that, but I appreciate any ideas. Maybe it's how Google redirects? Is there a setting that could affect this? Some of my settings are inherited from Ubuntu Studio.

Thanks.
