Appalling Comments from Mozilla about tabs on bottom instead of top "With the number of user complaints from inept users who can't seem to follow precise instructions about using userChrome that "we" support volunteers (and Mozilla) are seeing here, I fully expect some limits placed in Firefox as to what userChrome can modify in future Firefox versions. "We" are recommending too many "fixes" for "restoring" real old features like "tabs on the bottom" that Mozilla killed long ago."

If you are going to quote a person how about giving them proper credit.

Thank you for finding my comments appalling. I don't work for Mozilla, I am just another Firefox user. I sometimes get frustrated over the silly comments that some users post under the veil of requesting support.

At least there is a way to change the tab-strip location, for now, but with all the postings like this that "demand" it be made easier I expect that Mozilla will be closing that work-around in the future. Mozilla is already retrieving metrics as to how many users are using the optional userChrome file, and has plans to retrieve snippets of that code to see how that file is being used; not too much of a stretch to formulate plans to figure out what & how to block specific types of code, thus ruining things for the rest of us.

Hi angelfire4xx, I think you're underestimating your abilities. Most of it is clicking buttons and minimal typing. You just need to be guided step-by-step. You can do this if you put your mind to it.

(A) Create a new chrome folder in your profile folder

The following article has the detailed steps for that (#1, #2, and I recommend #3)

https://www.userchrome.org/how-create-userchrome-css.html

I also created video for both Mac and Windows, on that same page.

(B) Set your OS to show file extensions

See Step #4 in the above article.

(C) Download the following file and move it into your new chrome folder

https://www.userchrome.org/samples/userChrome-tabs_on_bottom.css

(D) Rename the file to just userChrome.css

Mac: To make the name of a file editable, you can select the file in Finder and press Return, or you can "force-click" it if you have one of the new touchpads. Remove the -tabs_on_bottom part from the file name so you end up with exactly userChrome.css and then click away to complete the edit.

Windows: You can right-click the file, then Rename, then remove the -tabs_on_bottom part from the file name so you end up with exactly userChrome.css and then click away to complete the edit.

The next time you quit Firefox and start it up again, it should discover that file and apply the rules.

Success?

Just to add when you follow the shortcut and properly make the changes when firefox updates your tabs remain on the bottom.I did this maybe over a year ago and its working just fine.

OK got lots of time invested; Copied & pasted from shortcut properties box for destination for download. Got "userChrome.css" file renamed. See file similar to previous one used last year for FF in Windows 10. userChrome.css open w/ notepad looks familiar. No edits to it yet. Did not work yet. Tabs still on top. Is there some syntax/ switches that need to be edited in the .css text to make this work in Windows 7? Seems like the was an article that had me make some edits to fix this last year & I am *still* looking, & afternoon is shot.

Hi Rocky56, maybe we should continue in your new thread here:
