Add a custom useragent string for desired URLs or domains.
Custom UserAgent String is an extension that enables you to easily change your browser's user-agent by adding site-specific user-agent strings from the Options page.
Some features:
1. Add a custom user-agent string for each URL or website (domain).
2. There is an option to change each URL to a domain from the options page.
3. Toolbar popup has an ON or OFF switch button (left side).
4. User agents can be added to the options page (more than 100 sample user-agent strings are also provided).
5. For each user-agent string, you can either delete or disable it for future use.
6. To find a user-agent string you can either use a search engine (there are plenty of websites that provide a free UA list) or use the sample list provided on the addon's options page. This list includes more than 100 UAs for modern browsers and ranging from desktop to mobile platforms. This list is also available on the addon's homepage, FAQ section.
Note: to report bugs, please visit the addon's homepage (https://mybrowseraddon.com/custom-useragent-string.html) and fill out the bug report form.

- (2023-07-05) อนุบุตร โคเลิศ: It's work, many thanks
- (2023-04-26) Allan Carhart: It's great to have control over some of the passive information being sent to websites. Here is just one of the many use cases: If you open a Google-owned website using anything besides Chrome, they shove an obnoxious message in your face about switching to Chrome. Even if you're using Chromium, which is literally the same code, they still tell you to switch. There is no "do not show again" button or any way to turn it off AFAIK. This Custom User-Agent string makes it easy to tell Google-owned websites that you're using Chrome even if you're using another Chromium-based browser thus shutting off the obnoxious message. Reply

- (2019-09-08) Mahdi Golestaneh: no wildcard support no updating for browser ver. 2 star just because open-source transparency no option in menu
- (2019-08-11) Muliawan Johor: This add on is useful to behave a desktop browser like an android phone, particularly on sites like instagram so that I can upload photos from my disk drive. Unfortunately, you are unable to tag people, set place, and upload multiple photos.
- (2017-12-27) Jeremy Ang: I think it does what it says it does, but terrible UI/UX. Suggestions 1) The one-true-button's on-click menu should let you switch user agents for the current page, rather than only having a link to the settings page 2) shortlist some sensible UAs representative of each platform for this menu
- (2017-10-21) Артём Виноградов: Класс! Очень актуально для браузера Vivaldi - которого отказываются многие сайты поддерживать, пока не сменишь User Agent. 5 звёзд ребята.
- (2017-08-30) William Situ: Works well but would be better if an entry supported multiple URLs for a single user agent so I could paste them all at once instead of one at a time.
- (2017-07-09) ivan kosenkov: можно 0свои агенты дописывать если вдруг нету нужного но там и так много засунули
- (2017-02-18) Andrian Andersen: Need sometime to actually to figure things up. But once done, this extension works really well on URL/domain basis.
- (2017-01-11) Ndianabasi Udonkang: Very useful extension. We deployed it accross our office for tracking staff visits to a particular company domain.
- (2016-05-29) Nyarlathotep: Работает. Надстройка под каждый сайт.
