Until a certain version of the browser, the history sidebar was one of Firefox's best features, in my opinion. It's one of the reasons I never switched browsers.
In the internal search field of the history sidebar, I would type, for example, the website "google.com," which contained dozens of records of searches I'd made. Then I'd press TAB, I think, twice and select the first history record, then I'd press CTRL + A, selecting all the history records, which were the results of the search. That's it, I'd press Delete, and delete everything. In less than 5 seconds, I'd execute this sequence of commands and clear all the records for a specific "site"...
Now it's horrible: pressing TAB once selects the Clear button, twice selects the Open Menu button, and three times focuses on the first element of the site on the right. Now, to delete the records, you have to do it one by one; it's terrible. It's a huge regression; it's the same or similar to Chrome, which I always hated.
