I want my Locator bar autocomplete cleared. I use my computer for both personal and business and don't want my history showing up on screen share meetings when typing in the browser. Firefox 40.0 on Mac (Yosemite). I go to: - History - Clear Recent History - Browsing & Download History - Click 'Clear Now' Firefox crashes (beachball), wait several minutes, still not responding, has to be 'Forced Quit' via OS X Re-open Firefox, Locator bar is still auto-completing. History still there. Booted into Safe Mode, disabled all Add-Ons. Still crashes and does not clear history. Disabling the autocomplete in the locator bar is not a solution. It's a poor workaround. If there were a folder or .js I could delete in the file system, that would at least be something, but I have found nothing on these forums that instructs on how to do that. The only solutions are to disable Add-Ons, boot into safe mode, click the same "Clear Recent History" button that crashes the browser. In trying to fix this, I have had to wipe out all my open tabs, re-configure my workspace, all of this costing me time and money. I use Firefox because I'm a software developer and it has the best tools for development, but it increasingly tries to be a consumer-oriented browser, like Chrome or Safari, and I hate those intensely. I don't want that. I want something that is a developer tool.
