Firefox Setup 125.0.2.exe popped a flag on Jotti's malware scan: ClamAV: Win.Trojan.Spora-7724442-0 I know this is going to turn out a false positive because VirusTotal came up with no flags but can someone at Mozilla get this flag cleared at Jotti's/ClamAV ? thanks

I made a post the other week about issues I was having with Firefox & YouTube.

Having put the browser in safe mode I discovered that it was my ad blocker/s. That said, I had notice Firefox lagging or loading hard on video sites, not just YouTube as well as some applets on other sites. And having experimented with various ad blockers and video sites as well as my own blogs, I find that I am not having these problems with ad blockers in Chrome or Edge, but only Firefox, so much so, that most of these sites are entirely unusable unless I disable the ad blocker/s in Firefox.

Frankly, I've been noticing it for some time, but as of the other week they have nearly rendered the browser unusable, or the ad blocker/s unusable in Firefox on said sites. I have completely uninstalled and reinstalled the add-ons, from the Mozilla site, to no real avail.

It is not only annoying but very frustrating and I am about to give up, on the browser altogether. I am not having these problems with the same ad blocker/s in Chrome.

I've spent nearly two weeks on this and it hasn't gotten better.

There it is. Thank you.

I like to clear the cache on a regular basis but then Facebook does not recognize my laptop and I have trouble logging back on. Is it possible to clear the cache for all but a select website? Thanks

I have used for many years Java in Firefox to stream live a stock market app. In order to continue using that app I have to use now Microsoft Edge. I would prefer to continue using Firefox. Is there a solution?

I don't want the pdf to save to disk without my will when I open a pdf file from any website. Fire Fox saves the file first, then opens it for reading. How to change it? I want to read the pdf first and then decide what to do with it. This works similarly in Edge. FF is my main browser, I wouldn't want to change that, but I have too much garbage on my disk. every pdf is saved first, completely unnecessary.

I know Firefox recently changed some settings regarding automatic downloading of files, but I need to know how to stop Firefox from automatically downloading .pdf files that I view. Sometimes I just want to view a pdf without downloading the file. Firefox keeps automatically downloading the file, then after viewing it, I have to manually delete. I don't to do this! I just want to view the file and if I want to keep it, I'll save a copy. This is extremely annoying! Can I change the settings so that the file won't automatically save to my computer? Thanks

I'm using Firefox Version 98.0.2 on Ubuntu 21.10 with Wayland and Gnome 40.4.0. I choose a larger cursor size from Ubuntu's Settings->Accessibility->Cursor Size. However, in Firefox the cursor always displayed in the smallest size.

Before the new update whenever I downloaded a file it would ask where to save the file to every time, now it just asks once then automatically saves any new files I download to the same folder as the previous ones, forcing me to then go to that folder and manually move it to the correct folders. Is there any way to change it back to the right way it was done before they decided to remove our choice? My setting is set to "Always ask you where to save files", with the emphasis on "Always".

Hi there, I'm hoping someone can help with this. I recently signed into a shared computer with my personal Firefox account, and it automatically imported all my history, my browser extensions, and bookmarks, including personal/secure information that I wouldn't want on a shared computer. I tried signing out and deleting the sites and login information, even going so far as to completely delete all of my browsing history and cookies and signing in with another account, but all the supposedly deleted history and logins and extensions were then transferred to this second account. I have deleted all my data, even uninstalled and reinstalled Firefox, and all the data from my personal account keeps haunting me as suggestions when I type in the task bar or suggested usernames when I log in to websites. How can I actually delete this information so it's not on a shared computer? Thank you!

Updating to version 98.0 onwards Firefox has started saving a copy of every pdf file I view (open) in my downloads folder.

My settings have not changed:

Tools->Settings->General->Applications: - pdf (application/download): Always ask - pdf (application/force-download): Always ask - pdf (application/pdf): Use Adobe Acrobat DC - pdf (application/x-download): Always ask

And when the "ask" dialog pops up, I choose "open".

I have tried all standard methods/troubleshooting, including resetting the handlers.json file.

The only way to avoid getting a copy in the downloads folder is if I choose "Open in Firefox" (application/pdf) instead of "Use Adobe Acrobat DC".

Any solution to this?

Thanks Michael

Firefox is becoming more and more buggy and more unstable using more than 8Gb of ram in either the apps processes or if not there then in the background processes and when you look into the firefox task manager it reports it is using no more than maybe 100 MB of ram the only way to stop it is to close the one process that is using all the memory. when i investigate using the about:memory function it tries to tell me that it is an extension using the memory but if i disable the 2 extensions i use and reload the measure memory it still is using exactly the same amount of memory. is there any sort of fix for this because i am getting sick of having to have the windows task manager open to close the rogue process every time i use my browser

I know firefox version 98.0 changed how downloads work, but I have my settings for downloads set to "Always ask you where to save files" and specifically for PDF files, I have the action set to "Always ask". However, when I click download on a PDF file and then select "open with firefox" as the action option, the file not only opens in the browser, but also gets downloaded automatically without even allowing me to select where. Is this intended behavior? There are lots of times I just want to view a file and not actually download it, and this is quite annoying.

My address line is red, and their is an icon which say: browser is under remote control, reason: DevTools.

I am not sure how to fix this, or what to do about this. I do not know if I caused this myself. Please let me know if anybody can help.

The Send Tab/Link to Device feature only works in one direction, from iOS to MacOS. iOS to iOS never receives, although the popup says it sent. I'm using Firefox 98 on MacOS and iOS. I have a Windows 10 PC which can't receive or send tabs/links as well but I'll limit it to the Apple devices for the moment.

Sync and notifications are enabled on Laptop, iPhone, and iPad. I've de-synced and re-synced each device separately and together. I've attempted to send between each device separately and all together.

Neither iOS device can receive tabs/links from one another, nor send to each other. Laptop can receive tabs/links from both iPhone and iPad, but not send to either.

Each time I re-sync an iOS device I get a notification on the Laptop saying that "this computer is now connected with Firefox iOS". But still nothing works.

Firefox used to give the option to open a file without saving. Now it saves everything to my downloads folder with no option to just open. (I am aware Firefox used to save the opened files in temp). This causes major clutter in my downloads folder and big disruptions to my work flow. Sometimes I just want to view the file and not save it to my working folder (downloads).

Is there a workaround to save to opened files in temp and the saved files to download?

Does Firefox give 2 different "save to" options? One option for a location to save downloaded files and one option for a location to save opened files?

Hi! Since updating Firefox to 98.0 I've been experiencing sudden performance drops(lags/freezes/stutters) while scrolling. `about:support` page shows that compositing is `WebRender`. The issue occurs with fresh profile without any addons installed and also in `firefox-nightly`(100.0a1). However, scrolling is totally smooth in 97.0.2 and earlier versions of Firefox.

What changes in Firefox 98 could cause this, and are there any settings in `about:config` I can try to tune to solve the issue? These are the settings I've always used, and, as I mentioned, scrolling was smooth before 98.0:

gfx.webrender.all = true general.smoothScroll.mouseWheel.durationMaxMS = 400 general.smoothScroll.mouseWheel.durationMinMS = 200 mousewheel.min_line_scroll_amount = 40 mousewheel.system_scroll_override.enabled = false

I want to set a timeout for the master password. It's clearly a security threat to leave passwords unencrypted. It bothers me more than being prompted for the master password.

I remember we used to be able to set the timeout and it's a pain to go and logout the software security device after logging in to the one thing that needs the master password.

A customer shared his Firefox login with me to share his passwords. I logged in with his account, downloaded his passwords and logged out directly afterwards, but now he is reporting that he has ALL my passwords. How can undo this? I never gave him access to my account and I never clicked on sync or something?
