Frequently Asked Questions

Got questions? We've got answers

Does Flexitter work on the new X.com?

Yes! Flexitter is designed specifically for X.com (formerly Twitter). It works on all pages including your home timeline, profile pages, and individual tweets.

Is my data collected?

No. Flexitter operates entirely locally on your device. Your preferences are saved in Chrome's local storage. We don't collect any personal information, browsing history, or usage data.

Will it slow down X/Twitter?

Not at all. Flexitter is lightweight (under 40KB) and only applies CSS styling changes. It has minimal impact on page performance.

Can I use keyboard shortcuts?

Yes! Press Alt+0 to toggle Focus Mode (hides both sidebars), Alt+1 to toggle the left sidebar, and Alt+2 to toggle the right sidebar.

Do my settings persist?

Yes! All your preferences are automatically saved to Chrome's sync storage, so they persist across browser sessions and even sync across devices if you're signed into Chrome.

Can I reset to default settings?

Absolutely. Click the "Reset to Defaults" button in the Settings section of the extension popup to restore all settings to their original values.
