Hi,

I use Mendeley Web Extension to pull articles and other things from Firefox directly into my Mendeley library. I will usually rapidly read through the PDF file online before deciding to add it or not. For some unknown reason, Firefox blocks the use of Mendeley on PDF file, for security reasons, and I can no longer add them to my library. Most references are only available as PDF files making the add-on completely useless. Is there a security feature that I can disable to be able to use the extension again?

Kind regards,

Mathias

Unable to complete backup of firefox profile because of over-length file names in storage sub-directory. Is is ok to simply delete one or more file names which are old URL's and no longer required? Clear History All doesn't clean them out. (Firefox 101.0.1 (64-bit) on WIndows 10) thanks

Hi! There are multiple recent threads on this issue, and not one of them has a solution, so I'm asking again. I want to increase the font size of the top header text, specifically the bookmarks toolbar, search bar, and tab titles. The text is too small for me to read. It would also be useful if I could increase the font size for the applications menu (the hamburger drop down menu in the far right of the header).

I do not want to increase the size of anything else, so changing layout.css.devPixelsPerPx is not the solution. I have changed my global zoom settings, and set them specifically to "Zoom text only", but this setting does not effect the bookmarks toolbar or the search bar. Changing the default font size also does not increase the size of this text.

Just to clarify again, these threads are not solutions to my question: https://support.mozilla.org/en-US/questions/1214027 https://support.mozilla.org/en-US/questions/1293358

Firefox says I need a video codec to play a video (that is aparently somewhere on the page). It does NOT tell me what video, what video format, or what codec I need. How do I find out what codec I need?

For the past few days I get the request to enter captcha characters every time I try to access the Amazon website using Firefox on my Win10 PC. It works fine on my Firefox for android on my phone and also works fine using the Edge browser on this PC.

I've tried resetting Firefox. I've tried troubleshooting mode. I've tried turning off enhanced tracking. What else could cause Amazon.com to feel the need to verify that I am not a robot ?

Audio was working fine until recently. Now, firefox has no audio playing on any site.

Some sites show "PLAYING" in tab, but others like YouTube don't show that notification. Even with "PLAYING", there is no audio output.

I checked Windows settings and Firefox is set up correct (and the same as it was before it stopped working), see screenshot attached. Otherwise, I restarted Firefox, tried it in troubleshoot mode, and reinstalled Firefox. No changes.

Possible system changes include: Maybe a Firefox update occured and broke the program? I installed the game Civ5 from Steam which required some Windows VS redistributibles installed.

This question has to do with logging into web sites with an email and a password. Firefox 101.0.1 (64-bit). Windows 10.

On many sites, when I click in the email field, a drop down list of email addresses appears from which I can make a selection using the mouse or up/down arrow keys. Some web sites have as few as two email addresses in the drop down list, others have many more. I recall that one site has about fifteen email addresses in the drop down list.

How can I remove a non-applicable email address from the drop down list?

How can I clear the drop down list of all email addresses?

Thanks.

My workflow in Firefox involves 100's of open tabs pertaining to work, personal etc. I regularly bookmark all the abs using the 'bookmark all tabs' feature in the Bookmarks drowdown (or the equivalent 'select all tabs' -> 'bookmark all tabs' by rightclicking on a tab) which offers the option of saving the tabs in a new folder name I specify. As of the last couple of weeks, the option to enter a folder name no longer exists. I've attached a screenshot of the current pop-up when I choose 'bookmark all tabs'.

Perhaps related: this may have started occuring after I upgraded to the latest version (v. 101.0 on MacOs 12.4 on Macbook Pro) or the timing may be a coincidence.

Saving the 100s of bookmarks every week is an essential part of workflow; I've been doiong it for years, and I really need to have this ability back. Please help me debug this.

Thanks!

I'm trying to load a temporary add-on on my browser, but when I click the button "Load temporary add-on", nothing show up.

I tried to look for errors in the console or debugging tool, but nothing. With snap, I removed with the purge option my Firefox and install it again, but the issue still appears.

Some technical details: Ubuntu 22.04 LTS Firefox version 101.0.1 (64-bit) Mozilla Firefox Snap for Ubuntu canonical-002 - 1.0

Hi,

I am signed into a Firefox account. I have used this account on at least three different computers. I have downloaded the application anew at least a dozen times.

Firefox randomly, from where I sit, opens things in French rather than English. How can I keep it in English unless otherwise specified (I occasionally want German or Japanese)?

Thank you.

best, Sea

Hello. I just closed by accident my main window so I restored it, but it apparently lost all the container data and restored all non-pinned tabs to the default container.

Is it normal, is it a bug or is it a yet-to-be feature?

It feels like a bug because pinned tabs (which were not present/open in the secondary window that stayed open when I accidentally closed the main one) where duly opened in their respective containers.

I went to settings and set firefox to open links in a NEW TAB instead of a new window, but it still opens links in a new window. I did a search on google and when I click on the link for the website to see the information it is still opening in a new window. How can I fix this so I don't have a lot of new windows. It's irritating to have to close all those stinking windows just to get back to my original window. I just want the links I click on to open in a new tab.

Instacart webpage suddenly will not display/open on Firefox but can display fine on Chrome. Instacart App on mobile phone works fine, just won't open in Firefox. Any suggestions other than using Chrome? Firefox version 101.0.1 Windows 10. Was working fine until latest update installed this morning.

How do I enable Javascript on Firefox Android? There are many so-called solutions on the net, but the one with "about-config" does not work; it just starts a search. According to mozilla it does not work on mobile devices anyway. So, does anyone really know? Cheers

How can I set my location in Firefox. I know better than anyone on the web where I am located, and Firefox is locating me hundreds of miles away, so I just want to set the Zip code for my actual location. Thanks for any advice! -Harry

Following direction on Help Page - Trying to sync tabs, bookmarks etc from one laptop to another. In settings, devices are said to be logged in and sync set to sync pretty much everything.
